Search Results: get my boyfriend for his birthday

Let’s start by saying my ex boyfriend came to Europe with me for my birthday after I told him i would go alone.. Our first day I got a bit jealous of two women he met through a group at a bar who are just friends and accused him of dating one of them and he said he’s not dating anyone. Then night time came and we got drunk, we spoke about one of his siblings dating (note: I am close to his cousin that’s how we met) since i was drunk I spilled the beans about this sibling and then he made a sly comment and then said he “dated” a “Russian “ girl who met his parents last year bc of his sister (she tried to get me to meet his parents after 3 dates ). I was blindsided since I never met his parents. I blew up and had a breakdown and left the hotel to go dancing and he text me while I was out alone he only went on a few dates with this girl and his sister tried to hype this person up. This is where it gets interesting (He’s never had a girlfriend and the one he counts as an ex he only saw 7 times and was long distance) Anyway, I come back to the hotel crying, of course, and he says to me, “Let me explain “ as he got up from the bed “I only said I went on dates with this girl since you kept using the word dating but i never dated her and she wasn’t Russian. I only saw her three times at the same bar my sister goes to and i deleted her number and don’t even remember her name. My sister was drunk and invited this girl to meet my parents when they were in town but i only had meetings with her at the bar & got drinks i never took her out to dinner or a proper date she was a random girl and i only saw her 3 times in the four weeks.“ I then i asked if she was introduced as a girlfriend or date and he said “my sister got excited and wanted to hype this girl up to my parents for me but didn’t go well bc they didn’t even like her. “ I haven’t spoken to her in months and it was last May”

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?
