Search Results: ask him out on his birthday

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?

I know of at least 4x within the last 6 weeks that he went golfing or out to drinks and told me it was a guy or two when in reality it was them and 2 female coworkers and sometimes it was just him and the girl or girls. One of the times was my birthday dinner and the reservation was at 4:45pm. He told me he was going golfing with a guy coworker. I ended up having to run home to take his dog to the vet because he was reacting poorly to a recent surgery around 10:30am. Around 1pm he texted and asked if I minded if he grabbed lunch as he hadn’t eaten all day. I told him it was fine but the dinner. He showed up at 4pm noticeably tipsy. I found out that day he had gone golfing with one of the guy and 2 girl coworkers, and then continued to hang out with them drinking after while I was home carrying for his dog and getting ready for dinner. One of the other times he started around 3pm happy hour and I had met with a girlfriend to catch up that night and I was just up the street from our house, he got home around 8:40pm and started getting really upset I wasn’t home yet and what was I doing (mind you I met my friend around 6pm and had dinner). Come to find out he spent the day with the girls drinking. It’s the lying about who is with him, why lie, especially if I shouldn’t be concerned? He is always so skeptical of any male coworker of mine? He got upset with my team of 4 (all guys but me) did a golf team outing. Yet he’s secretly golfing and getting drunk with female coworkers? Is this a normal reaction?
