Sag w/ scorpio venus

I’ve been with this person on & off for over a year. we fight all the time & become distant, but they keep coming back. kinda surprised bc I thought sags would leave if it was too negative. im a capricorn with a sag moon & venus & pisces mars, forgot what all his stuff was other than sun & venus lol but thoughts?

What’s his moon? He comes back because he loves you, obviously. He just needs space but when he misses you, he’s back.
