Thank you for your comment - I appreciate it.
I've added my comment to the original description so that the whole picture is visible to other people. Thank you for recommending me to do that; I haven't been sure if that's necessary, so thank you for clarifying that.
I am not sure what exactly to comment or think on you writing that my friend is romantically involved in me. My friend is already in a relationship with another guy, and I think that after her kiss I made it quite clear that I don't want this to happen. To be honest, for me it is totally obvious that you don't go after people who are already in a relationship, so I don't want to interpret her actions in the light of her going after me. I like her and I appreciate our friendship, but why should she be romantically interested in me if she even explicitly said that she doesn't go after people who are in relationships? I just think it is a basic consensus.
But also, to be honest, if I would be my own friend I would also urge myself to caution. My partner has actually asked me before I went to hers and she kissed me if I was sure she wasn't romantically interested in me, to which I replied "yes, she definitely isn't, why should she be?" And when I then talked with my therapist later about it, I realized that she kissed me. So my judgment of people being romantically interested in me definitely isn't good (actually I only noticed my current partner being romantically interested in me when she began calling me "darling" and "love", before that I just thought we are good friends.)
My girlfriend already knows the whole story, and I also know she reads this thread (hi to you btw, u potato); it is very clear to both of us that we talk about this dynamic. I think that she does a good job by sharing her concerns with me, so I don't think she does anything wrong here.
I am not sure what to make of it. It just seems to me completely irresponsible and wrong of my friend if she is romantically interested in me to take actions in that regard when we both are in relationships. I can't really justify to myself seeing her actions in that light, because for me it goes against fundamental moral values I have. But I'm wondering now if I just tell to myself that she isn't romantically interested in me. Either she doesn't get the social cues like me, or she is interested in me. I'm not sure what of these applies though.
