Hey, I don't know if you'll end up reading this since it's been a while since you posted it. I just wanted to share with you that I don't think it's so much you wanting to get back together with him as much as it is wanting to understand what happened and get some formal closure. I am the same way, so I understand this, and for people like us, it is better to stay away from online dating because so many guys make a game of doing this, they sort of choose 4-5 girls to take out and see how fast they can get em hooked and then once they lose interest or find another prospect, they just drop out of your life.
I'm a girl but the majority of my friends are all guys, i'm in my early 30's, and they always tell me about the handful of girls they're talking to. They're all really legit, genuine, awesome dudes too, it's not like they're monsters looking to break hearts, they just don't take it seriously because it's online and there are so many girls to choose from, it makes it super easy for them to treat it like a salad bar.
Obviously I don't agree with them doing this but it's one of those things that technology has unfortunately just made so easy.
But yeah, even if they don't seem like the type to do that, they ALL are doing it. And since you meet them online, it's not like you know their place of work or friends or anything, which is why a lot of dudes go on those sites to begin with, so they are sort of free to peace out whenever they want, without any explanation, cause they know you can't really contact them if they block you and delete you from this or that.
It can be really crazy making, like for real, I feel you. This **** used to happen to me back in the myspace days lol, it took me a long time to quit meeting dudes online. But if you insist upon finding them on those sites, then the best advice you will ever get is this: whenever one of them just suddenly stops talking to you, or doesn't show up when you agreed to meet, or anything that is just generally a d*** move, DELETE their number immediately and whatever other contact info you have for them. DO THIS AS SOON AS IT HAPPENS. You are saving yourself by doing this. You are cutting the rope instead of hanging there with a broken neck. It's a win-win situation because you won't hold on or wonder or need closure, since technically YOU cut the communication by deleting their number and whatnot (psychology), so you get your own closure. But get this, if the dude turns out to be anything of value, he will end up texting YOU with an explanation or apology. Anyone who is worth even 3% of your time will at least make 1 attempt to contact you. If you never hear from him again, then it won't matter, and you'll know he was a pussy for not being able to tell you straight up to your face that he's not feelin it.
I think it's better to meet people through friends or work or whatever because it sort of gives them an obligation, in a way, like, they are way less likely to just ghost you because you'll see them again one way or another haha. Cause if you're like me, you don'r just want to waste time, even if it's only 4 dates, you're investing in someone and since we live in a society where people generally invest in nothing but themselves, then give yourself the upper hand and at least inadvertently make it so they have to be decent lol. It's sad that it has come to this, like man, people can't just be real and at least stay friends and keep in contact. I never been able to just walk away from anyone like that, even someone I hate, like I feel it's the right thing to do to at least talk to them in person and have a discussion. I'm old school though. People just want everything to be easy now.
You have a stellium in the 8th? My best friend does too. You guys generally want depth and are willing to even "work" at a connection, which is totally respectable. I think a difficult thing for you guys is understanding that something could just be meaningless and erasable for another person when every connection you make with someone holds some kind of meaning/value to you, otherwise you'd not seek the connection in the first place. I'm that way too, probably because I have a rather strong Pluto. I am still trying to understand how people I was very close to could just leave my life one day like it's nothing. It makes me want to never let anyone get close to me again.
Oh! One last thing! There's this site, it's called meetups.com or something like that. It's not a dating site but it's where you meet up with other people who are into what you're into, and it's way more authentic (internet wise) to meet potential partners, cause you go there already having common interests, and there's lots of people to meet and talk to, so you go with the concept of just meeting cool people who are similar to you and you never know what might develop from that. They have meet ups for anything from astrology, occult interests, specific music interests, hobbies, etc. Like for me, i'm a music producer and they have meet ups for people who produce house and electronic music like I do and it's cool cause I meet lots of different people to work with and make music with and stuff like that. I just feel like it's way more sincere and beneficial to you because you're doing what YOU like and naturally there are going to be people who click with you and think similarly when you put yourself around things you enjoy already. Check it out dude, it's worth a try. Might be better for you, cause then you can get to know people and how they actually are before you form any kind of attachment to them. People like us, ah, we gotta embrace the whole "friends first" concept, as boring and void of passion as it seems, it's the only way to maintain our sanity!
