Search Results: what happens next

This has happened for the third time
The first time was someone I worked with he was obsessed with me we had sex for around two weeks then he just went weird. The time we had sex first he lasted 3 seconds then the next time was about 5 mins and much better.

Then I had a date from someone who messaged me who is never met on social media and we had sex. He lasted about 3 seconds and I accidentally laughed at him. He did try to come over again but I was alseep by the time he got to my house. Then he tried again but I was fed up with him taking ages to reply.

Then the third was someone messaging me again and he lasted a lot longer about 5 mins first time maybe less. Then we had sex multiple times that night but again he’s ghosted me

Why does this keep happening? They all say I’m super pretty and the sex is amazing but then it ends like this. I do have 3 kids and don’t want a relationship and have said I’m not closed to it but not seeking it.

Am I that bad looking and the sex that bad?

My best friend (WHO HAS A BOYFRIEND) of 6-7 years kissed a guy i used to hook up with.
Background
The guy and I had a horrible falling out, he said awful things and never apologized for them. My best friend has seen me cry over this guy. A year later he comes back to hanging around the friend group. I have a boyfriend now and i love him so much. The guy came up to me and said “we are cool” even though he never apologized so of course I hate him. He also tries so hard to become friends with my boyfriend, but of course he isn’t having it.
I just recently threw a party for my boyfriends birthday. The guy ended up showing up because of the mutual friends we have. Of course my boyfriend and I did everything in our power to avoid him all night, and he would still try and talk to me.
When I was dealing with a drunk person during the party my friend and the guy went to go get food. She got in his car!!! Of course it's the one time I wasn't in the room. Like an hour later they come back into the party with food, then my friend comes and stands next to me and doesn't say anything. There's also a chance they went to the bathroom together. The next day I ask her what happened and she admits that they kissed. She claimed she shut him down but then immediately contradicts herself with her next text. This is not the first time she has displayed “pick me” behavior
I guess it's just never been this bad. Her boyfriend emotionally cheated on her a month or 2 ago and ever since then she has been manipulating him. I also maybe feel sometimes she might be jealous of me, not on no cocky stuff.

The cheating aspect aside, do we think I should or. Ever can forgive her. Should jus let that bridge burn no matter how long we have been friends?
