This is just my opinion--But I don't think he's worth your time. I agree with Phoenix that if he did that once that chances are greater that he'll do it again. I don't understand why he would do that to you if you have been more than open to fill his sexual desires. Sounds a bit strange to me..Something just isn't right. In addition, if he sought out another 'women' while you are trying to have a very serious conversation about how you feel, that is downright disgraceful. He should have been caring, understanding and supportive of what you were trying to explain to him rather than seeking out other women.
