will they break up

[Belatrix]

Hi everyone. I am in love with him, and i think he feels the same.We were dating some time ago, but some issues happen and we didnt enter in a relationship.Now, he is with someone else.My question is : will they break up?
I got this chart:I am Saturn and Moon, he is Moon and Sun. I am not sure what sing is she. Mercury or Venus? Saturn is in my 8th house in Libra( i wish us to be together). He(Moon) is in my first house in Aquarius under my rulership(he still has feelings for me) and makes trine to Saturn(i am not sure what that could mean.) Sun(his animal nature) is in my 9th, his 3th house in Libra in conjuction to Mercury(is that her? She might be his neighbor, or something like that)If she is Mercury, she ruler his second, 11th and 12th house. If she is Venus, she is in his 3th house in Scorpio, ruling his 3th and 10th house.Venus makes square with Moon (him). Venus and Mars are seperating in my 9th and 10th house.I dont know what that mean. Is she Mercury or Venus? And what is answer to my question? Will they break up, and when?Please help

Hello, welcome to the forum

I'll use the 1st house for him, and the 7th house for her, as you are not involved in the question as you asked just about him breaking up with her.

He is Saturn, she is Moon.

Moon has just trined Saturn, showing them together.
There is also mutual reception between them, showing a mutual interest too.

Moon is in the 1st house in Aqua, showing her being close to him, and he is welcoming her being her depositor. He also holds more of the cards in the relationship.

Looking to the 4th house from the relationship, I think this is the 10th house, Mars rules this and Moon squares this. This shows a 'no' answer to me.

If I also look to the natural 4th house, Venus, then Moon also squares this, another 'no' answer.

Did he show any signs that they may break up?

It is bad news for you, I'm sorry, but it looks like they are very much together.
