My son's ex is my daughter's best friend

My (49m) son's (22m) ex gf (23f) is a great girl who has been in our lives for several years. We met her when my son met her. She is a very kind girl who is caring and thoughtful. I'm so sorry if you hear a stepmom vibe here, because that's what she's like. She kept the house clean, cooked for him, and helped him out with a ton of stuff. I can't say enough about her. <br><br>When he introduced us to her, we were impressed by her right away. We would sometimes do family activities together and she would come along. She would befriend my daughter (18f) right away.<br><br>My son broke up with his ex a year ago, but she still comes over to our house to hang out with us. I've known her for several years and she's practically a part of our family. She is like a daughter to me and her parents have said similar things about my son being like a son to them. <br><br>I think a problem might arise though. My daughter is a senior in high school and is applying to colleges out of state and out of town. I'm sure my son has figured out by now that my daughter still keeps in contact with his ex. This is a big problem. He hasn't said anything but I can tell he is not pleased. He says he's ok with it but I don't think he is. <br><br>My wife and I have discussed this. We have no bad feelings towards his ex. While she's not our daughter, we love her like she's our own. She's been a part of our family, probably even more than my son has. I think my wife and I feel guilty because we like his ex more than him. I'm sorry to say this but after he broke up with her, we've realized how bad of a person he is. He's rude, loud, obnoxious, wasteful, spoiled, and lazy. He doesn't help with anything at home and he's selfish. Compare this to his ex who is just the opposite of all that he is. <br><br>We've discussed just not telling him that his ex is coming over when she does, but I don't think that's fair to him.
