I and my boyfriend are in a relationship from the past 3 years in starting we use to talk a lot on phone during night but from the last 4-5 months there is a lot of change in him he always gave time and attention to me he is really possessive but now I even caught him lying he went to movie with his friends and didn't tell me he very often goes out with his friends in the evening for having snacks and all. He thinks that if he'll tell me I would fight he says that he wants to enjoy his life as 12th is finished and he talks really less with me and avoids talking in night he says he wants to sleep and he can not talk as he will have ear pain I don't understand what has happened to him although he loves me but doesn't give me proper time even when he is free he thinks I am too quarrelsome and always fights with him I am really confused what is he up to if we don't talk fr days he really doesn't care as he has taken me fr granted I try to talk about it with him but he is never interested in talking about it what should I do? I love him a lot an don't want to lose him please help me how can I get to know what's the matter he has lost interest in me or what?
