I've been in a "relationship" for 15 months. I was previously married for two decades and now am a single. When I met the BF he adored me, was supportive, couldn't keep his hands off me ~ sex was great and frequent. It dwindled a bit after 3/4 months. At 6 months it ceased completely. He went into a depression for several weeks and we had no sex for two months. We discussed the issue and agreed that he would stay over once a week and would have intimate time together. For the next few weeks he made excuses 50% of the time, on the days he was due to stay, claiming he was tired or unwell. The frequency of sex is now down to less than once a month. I can't stress how rejected this makes me feel. I don't even get a hug or kiss now - he hasn't touched me for the last three weeks. I am just not sure what to do. He gets very angry about trivial things (with me and with everything) and criticises me a lot. On the other hand he would do anything for me (apart from show any intimacy). He is 50 and has not been in a relationship for longer than 2 years. One girlfriend dumped him due to the lack of sex. Another had affairs due to the lack of sex and dumped him due to his constant criticism of her/plus lack of sex. I have tried to dump him but feel I love him and he is basically a good person. He says that his sex drive is low and dwindles after a few months in all relationships. A friend of mine said "well he only wants sex when it is part of a conquest, an ego boost for him, He can't be bothered now that he knows he has "got" you hooked". I feel this is true. If he feels he is lod=sing me he has sex, but most of the time he just can't be bothered.
