It's 5am and I can't sleep. I've been with my boyfriend two years and we've done alot together .He's usually very sensitive and loving. I believed he was the love of my life. It was only three weeks ago he said he wanted to live with me and we should contact estate agent to start the process. Then.out of the blue he just went cold on me and didn't contact me. He missed valentine's Day and our two year anniversary . I texted him on valentine's to say did he get the present and card that if already ordered. He just replied " yeah thanks". The day after I went to his house and found him just sat watching TV alone. I asked him what is wrong and he said he just needs to be left by himself to think for a while and he can't deal with any emotion right now. His voice was flat and his expression emotionless. I was there less than five minutes and he asked me to leave as he was " tired". So I hugged him, he didn't hug me back, I told him I loved him and he said nothing. There's been no contact since. This is a man who talked of marriage,live with me, etc. He has a very good job which can be stressful but surely that's not the reason he's like this?? Am I to presume the worst?? I'm so confused and feeling lots of heartache. I don't want to hassle him so leaving him alone as he asked but what am I supposed to do?? I sent a text two days ago just saying hope he's ok. He read it but hasn't replied.
