To start this off, I knew my best friend, Heidi, from college and we were friends for all those four years. We were very close, we took summer vacations and we were roommates. Summer after college, I moved to California with my husband and I had some problems getting pregnant after my first born son. I had adopted a boy who had only been a decade older than me. I understand it's a bit weird for most people, but it's only because I sympathized with him and his story reminded me of my mother.

Anyway, cut to a decade later, I'm divorced and I move back home with my older son who is in graduate school now. I decide to reunite with my friends of which is Heidi and another who is named Felix. The thing is, Heidi had DRASTICALLY changed. She had told me of some guy named John that she was having a sex-only relationship with and I didn't think much of it, but it shocked me cause back in college she had been a very committed person. She had also become very forceful and less affectionate from the person I used to know. I think it may have been due to her parents passing away or something, I don't know.

Before our reunion dinner with Felix, I had introduced Heidi to my son at his baseball game. After about a month , I went to drop off some things at my son's place (he gave me a key) and found my son naked on the bed and Heidi had been standing there, fully clothed, but I immediately knew what had been going on between them. I knew they had been involved ever since I introduced them because my son had asked me a bunch of questions about her. Heidi then tries to tell me she was there to break things off with him because she realized how unfair it was to me. I couldn't bother to hear anymore. I just walked back out the door.

I didn't know what to do or think, so I had phoned my ex-husband and he admits knowing that my son actually has a thing for older women and didn't bother to tell me???? And he thinks that what Heidi and my son did wasn't wrong, that he knows what he is doing, but I don't think he does! He's young, all these women could have mentally messed him up. My ex then tries to tell me that I'm the reason he is so caught up on older women, that I had spoiled him too much, but he is my son, of course I'm going to dote on him.

Heidi then tries to victimize herself by saying my son pursued her, but she said yes to him. She had been selfish and did not care for my feelings. She also said she didn't want to hurt me by telling me all about it and that the whole thing was consensual and nothing but lust, but that doesn't change what she did. She then tries to tell me that I'm overreacting about the whole thing.

I then also confronted my son who also said I'm overreacting and that it's none of my business and I shouldn't be this hurt by all of it. But it hurts because I love my son and I love Heidi despite how much she had changed and in those moments where I didn't much like her.

Am I crazy here? Am I missing something? Why is everybody making it seem like my son getting involved with my friend is not that big of a deal?
