composite chart

I'm new to astrology and charts so I want to learn more about them but right now I'm a little bit confused about the composite chart I have with my boyfriend. Do you think this relationship will last and what feelings could he possibly have for me based on this? Any explanation and details would be appreciated

P.S- many of our fights and problems are because I don't trust him because he was a player and his natal indicates player placements as I saw. What do you think about this?

The moon/mars/uranus conjunction attracts you but is explosive, and it's probably what accounts for the fighting. Neptune on the south node shows that suspicion, deception and illusions are a weak point.
The mercury trine Jupiter softens things up, as does Venus squaring the volatile conjunction.

Thank you
