For some context, I am American and met a man from the UK online. We have been in a relationship for two years, met for the first time in person over a year ago now. applied for a visa to live with him, I am here with him now.

The female coworker in question started about a year and a half ago. From the start, there were issues, but he says it's nothing.

-he planned a 5 day camping trip before we first met in person with "just the guys" to which I was ok with.

About a week before he mentioned bringing her along, to the just guys trip. To which I did not feel comfortable with, especially as they would all be sharing a tent. He said "she's like one of the guys it will be fine" he did not end up taking her, we had a big fight about it

- we meet in person for the first time and I can see on his phone he texts her a lot outside of work, often late at night. Again, I express how uncomfortable I am with that and want it to stop. He claims he did, but I was unable to verify.

- he never used to go to work parties, well he wanted to go to one and get a ride with her to and from so that he could drink. He isn't a big drinker. I say I'm not comfortable with this, another fight happens.

- I see his texts after the dinner where he texts her

"you should have made a move on me when you hugged me" and she responded with "I love you we only have one night together we should have made it count" I confronted him, he said it was just a joke and didn't mean anything

- a few weeks later he informs me that he will be ride sharing with her two times a week. I tell him I'm not ok with that, he does it anyway.

- I had to fly back and wait in my home country while the visa was being processed. He tells me he wants to start ride sharing with her 4 times a week. I am absolutely not ok with this. He claims he has stopped giving her rides

- he comes to visit me in my country while we are waiting the visa. I see once again on his texts that he was meeting up with her outside of work, on several occasions after I went back to my country. He never told me about this. Still denied it for hours after I confronted him with proof. Then acted like it was no big deal

-

- -I tell him I want him to stop all contact with her outside of work or I'm not coming back. He agrees.

- That was a lie

- after he goes back from visiting me, I find out that she talks down to me when texting him. He stayed for two extra days in my country, she asked him why saying "oh because you're so in love with her" with a very sarcastic tone. He said no the weather cancelled his flight that's why he stayed longer

- I return now having the visa, things are ok. He has several work parties coming up, somehow I can't go to any of them. One night he randomly tells me he's getting a lift with her to the parties. I flip out, I thought that he had separated himself from her. He hasn't. I tell him I'm not ok with this. Another fight happens.

- I talk to his mom, she says that she even asked if there was something going on between them, to which he said no. She says that "she's just a friend he doesn't see her in a romantic way"

- the last work party he said I could come, but he didn't invite me. I went, met her, and her new boyfriend. He informs me that she offered to give us both a ride home if we wanted to stay and drink. I said no. He tells me that she has invited both of us to come hang out with her and her boyfriend, I say no.

- He says I am overreacting to all of this, that it's nothing, she's just a friend, she has a boyfriend etc.

- I feel so lost, and hurt, I really thought he was going to cut back with her but that has not been the case.

- I'm at my wits end as to what to do anymore. I don't know if I am just being overdramatic like he says or if what I am feeling is valid.

-

- Anyone here been through something like this? Any guidance is greatly appreciated, as to your honest opinions

sorry for the novel, I needed to get this out somewhere
