Sounds familiar confused. Harleygyrl has some good references.
I've had the same problem with my mate for only 8 years though. Love em and nothing comes back. Or they might try for a few days and then right back to the same ole stuff.
What to do about it??? Good question. I was pretty bitter about it until I went back and forth with a few people on this forum. Helped a lot. The bitterness is gone but the problem remains. Harleygyrl and a few others on this forum will help you get through it or at least allow you to maintain until final resolution is attainable.
There are some people that just can't love. So be it....It's NOT your fault. Makes you kinda feel sorry for them. So I just keep the love flowing for the sake of having the love flowing. I expect NO return. It's fun.
