We have been seeing each other for a while and I' starting to have feelings for this guy. It feels like he really sees right through me and understands what I've been through. We seem to have so much in common also. Is our synastry a good match or is it just the planets in 8th house playing a trick?
I have attached our charts below. Thanks in advance
Having personal planets in each other's eighth houses often spells good chemistry. That's never a trick. And not only are his personal planets in your eighth house, his sun is in your eighth. Looks like the chemistry is mutual.
However, astrology can't tell you what the quality of your relationship is. Synastry shows potential. It doesn't show how you respond to that potential. Two people with good chemistry can have a wonderful, loving relationship... and yes, often highly sexual... or they can tear each other apart. Chemistry keeps people in good relationships, and also in horrible, abusive relationships.
Your best indicator of the quality of this relationship is your own observations. You know you have great chemistry with this guy, it doesn't take astrology to tell you that! As for the rest... how does he treat you? Do you have good reason to believe he's a good match for you?
