Venus in Sagittarius + Venus in Gemini = ?

sorry for long post!
I am a Scorpio female dating Taurus guy.. Usually I get along fantastic with Taurus', I always seem to date a Taurus. This one on the other hand I cannot get around. He flees emotional conversations, he's kinda boring, loves staying in watching tv and playing video games, does not go to bars.. before we started dating though he was back and forth between exes, like he wanted to have them both. I don't even think he is still over them. He is very witty, handsome, loves to be funny but he lacks any sentimental layers. We've been dating 5 months and still on one layer, being a water sign I like my emotional depth and understanding. He says I love you but I feel like he lies about things (I live with him, It's hard to hide things but I'm still paranoid). He has even said he hated telling me the truth cause he knows i'll get mad! I have a feeling its the Gemini in his chart and the aquarius.

his:
Sun Taurus
Moon Taurus
Mercury Gemini
Venus Gemini
Mars Aquarius
Jupiter Taurus

Lilith Virgo
