Hey!! I have been in a relationship with my childhood friend for the past 5 years. It's been 2 years since he moved to my apartment and everything was going fine. But recently I noticed some changes in his behavior. I don't know exactly what's happening but I feel like he is avoiding me these days. It's been few months since we had a good communication or sex. I wonder if he has another relationship. I have seen him with one girl many times during his office hours. When I asked him about this, he just yelled at me. He asked me not to interfere in his personal life. 

It was our 5th anniversary last day. We used to celebrate it every year but this time he refused to celebrate. He said he is not interested in any kind of celebrations. If this situation continues, I'm sure we will end up in breakup. I can't imagine losing him. I have discussed all these issues with one of my friends. He said that it would be better if we go for couples therapy from Toronto. I have asked him to talk about this therapy with David. I hope he agrees to come for this therapy. I don't think I will be able to survive the breakup. I'm trying my best to save my relationship. What else should I do? Please help!!
