why is cap pushing me away when he is in love.....

My cap has a venus in cap.we've been dating for almost a year and in the beginning he was sorta chasing me and would contact me pretty much everyday and would like my pictures on fb etc.But these last couple of months he's been super distant after he told me he has strong feelings for me...contacts me once every week,starts getting very cold and almost mean like as if he doesnt care about it,doesnt like anything o my fb and when i comment on his fb stuff it's like he doesnt acknowledge ue.he is treating me like a stranger and i don't get it at all😢He told me he was in love ,hes never open about his emotions ,ever! and he finally opens up and then completely shuts me out of his life afterwards.We also didnt talk for two months,cause he stopped initiating so i stopped ocntacting him because i dont wanna look needy and after the two months he suddenly messaged me and said he misses me and he's sorry and he wants me all to himself and doesnt want me to find another guy and that shocked me but then i dont hear from him for two weeks again and then after two weeks i hear from him and then i dont hear from him again for a week in a half.And the thing that hurts me the most is he has time to joke aroud with ALL his friends on fb ,he interacts with all his guy friends and girlfriends on fb freely and jokes around and he cant even like my post on his wall or acknowedge me talking to him on his fb.It hurts so much.I feel like a strager.Why is he ignoring me like this?It's as if he's scared of me or something or he hates me 😢I don't understand why its so hard for him to communicate,why is he acting so hot and cold? 😢I'm so hurt and tired of all of this,i;m emotionally drained 😢Please help guys,what should i do? 😢

Wouldn't it be nice if Cap men had a users manual!

Thanks for the advice guys.He's just really insecure and he told me he has commitment issues,he said he always saw relationships as never working out and all he kept getting from relationships was getting hurt 😢
