This woman (Betty) 29F and I (28M) have been dating for 3 months and its been amazing! We have a strong relationship but that has recently been shaken by three exes from her past (all of whom she has blocked).

Recently she got assigned a coworker Ryan at the tool service desk (works in an Engineering Company) because she's been manning it alone and it has gotten super busy.

I was ecstatic about this since she finally gets some support. Her job is support/service and some of the stressful times with terrible people causes her to be emotionally exhausted (lots of ppl take out their frustration on support/service workers) and since Im an engineer at a different company I get it. I once made a joke about "do you not have work friends?"

Well she took my joke a bit seriously and started befriending two dudes that work with her. Ryan is one of them and they work closely for 8 hrs a day. During the stressful moments she'd call me after and she tells me how supportive/helpful I am. Recently she speaks about how helpful Ryan has been. She has mentioned how they've eaten together and she has bought him food and such. In addition, we are watching now an anime Ryan and Jim(another coworker) watch. She also mentioned Ryan has a girlfriend who he is considering proposing to. What recently bothered me is that she buttdialed me twice accidentally and in both calls I heard her and him talking as I just kept saying "hello" and they waited for the shuttle together and chitchatted a lot. She even texted me during the call??

I guess it just bothers me that she is getting closer to a male colleague. She has often lied in the past about related things (she once met an old colleague for a work thing and told me they were just friends, but later it slipped they had a dating history). I realize that she is a female in an engineering firm so she will have to deal with men.

Key point is my trust in her is really low. I guess because of past betrayal, I'm hyper aware and trying to nip anything in the bud before it happens. There is also the fact she has dated or been involved with 3 coworkers/employees from that company before and has lied about it at first or hid texts in the past also make me nervous. She has emotionally cheated early during our dating phase.

This morning I just mentioned that Id like it if she could create some distance between her and her coworker Ryan. Do some combination of: eat less together, put headphones on, socialize less, take breaks away from the desk and walk separately to the shuttle.

When I said all this she seems exasperated and said you wanted me to have friends at work. He's dating someone. She said she'd try to tell me somethings she doesnt like about him. I just replied saying, "Look this is how I feel and I am not accusing you, but would love if you could make an effort to distance yourself and make me feel more at ease."
