So, for context, I am a 27m who lives in the United States, and she is 24 from the United Kingdom. We met 3 years ago on an app called Whisper. We were both doing pretty badly at the time due to us both having relationship issues. We ended up talking and bonding really well over the first 2 months. We actually had a moment where we thought of trying for a relationship. But we didn't and ended up getting back with our previous partners.

So, a few months back, her and her partner got into it. He is a super insecure and jealous type. And he accused her of not loving him because she wasn't spending time with him. (She is a chef, by the way, and works crazy hours.) Every day, I asked if she was ok and how the relationship was fairing. She'd always say it's fine, but she wished it was better. I would talk to her and try to give some advice. Well, one day, she's made the decision to get back on Whisper and post about her feelings. After doing that, she met a guy there and went on a date with him, but realized immediately that it was wrong and cut communication. A few days went by, and her boyfriend went through her phone and found out what she did. He confronted her, and she told him. Well after that she came to me and told me what she had done. I didn't validate her actions and basically chastised her for it, agreeing with her boyfriend that she was cheating or attempting to.

Once everything was squashed, I felt a bit used. She basically lied to me for a week telling me everything was OK, and then when she was caught red-handed, she came to me for a shoulder to cry on. Seemed like I was nothing more than an emotional landfill where she could just dump her feelings and not have any backlash. Well, I tried to forget about it, but after I noticed our conversation became less. She started only responding in 2-worded responses and messaging back much later. I've told her that 2-worded responses irks me because there is no conversation to be made with it. She said she'd do better but hasn't, and it's been 6 months, and no changes have come.

On top of it all, she's shown that she will prioritize her more tangible friends in the UK over me. She'd leave me on read all day and then message back before bed saying she was out and sorry. Lately, it has been like that a lot. And although I love and care for her to death, I can't just be her go-to when she just needs someone different than her normal to talk to. I feel that if I'm not on her side 100% that our friendship will end.

Should I talk to her about it, or am I being a bit over dramatic?
