Breaking up is killing me

I am a 50 year old dating a 22 year old for 13 months. He's much younger but very interesting and beyond his years intellectually. Problem is how we met, the back history. I met him through my 17 year old daughter, they almost dated 3-4 months later he and I stated dating. We talked for months prior. My daughter says it affects her to much to try to spend time with us. She said it isn't right since they almost dated. She at first tried to support me because she knew I was happy, happier then I have been in a long time. She just can't sit and try to pretend to spend time with us and be bayou. She says it makes her miserable. So I decoded that I would walk away. I'm in love with this guy. He's so loving and spends so much time with me. He doesn't worn but was planning to stay working soon. I pay fit everthing but a few gifts he gives me here and there. My family and friends feel he is using me. I'm a self dependent woman. I enjoy having every minute of the day with him. Today I told him that was it. He feels it has to do with my daughter. I also think from his comments that he will try to interfere with her relationship. He also said he would interfere witn any I may have in the future. I'm so sad to say goodbye, he makes me feel like the most beautiful woman in the world - he made me come alive. My daughter tried to be a good sport by going to dinner, the movies, general hanging out. She says it really bothers her. So I decided to walk.help me in really sad. Any comments pro or con will help.

"he made me come alive" - yes : this is the effect a young man or woman can have on an older person and it is very enjoyable - but is there anything that is of lasting value in this ? you and I know that such an infatuation does not last and with such an age difference nothing can be built you liked his "maturity" and intellectual capacities - but he still could be your son : why is HE attracted to you ? I would consider the fact of him saying that he will let nobody and nothing interfere : he seems to like your independence but at the same time he seems to want to "own" it - does he have some "mother issues" with his own mother that he transfers onto you ? as for your daughter - I can understand she's not comfortable this kind of relationship is fun to have - for as long as it will/can last : don't expect anything more out of it - that would be unrealistic - be ready and willing to give it up you may want to wonder how you can make yourself feel "alive" without the input of a younger person
