I have been in a relationship with my boyfriend for nearly a year and a half. I love him more than anything but... he is becoming too clingly, jealous and protective. He dislikes me talking to and spending time with my male friends and always gets mad at me when I go to parties when he's not there. But then he can go to FEMALE run parties without me and expect me not to care. One day he will be super happy and want to spend every second with me and then another he will not want to talk to me at all, but when he speaks to my friends he's full of conversation. Is he trying to get attention? He makes false accusations about me and constantly lies to my face.
I've thought about breaking it up but when I'm with him, I can't let all his good factors go.
How do you know when to draw the line?

" he makes false accusations about me and constantly lies to my face."

I would draw the line there. I simply could not be with someone who lies all of the time to me. Who is so possessive he does not want me talking to other males.
