I've bumbed into 5 total and 3 came up and say hi and we maybe get a coffee, the 4th girl we looked at each other but keep on walking past and not say anything.

Once I saw a wl at her place and she was playing cute with me cuddling and trying to kiss me when until the lift stopped, opened and an old regular (number 5 who I got bored of) randomly walked in, stopped and shot me a dirty but the sideway glances she was giving the other girl was like daggers (she thought she was my GF and was really jealous, these 2 girls dont work at the same shop so they don't know each other),

She messaged me later to say she will "expose me to my gf", I replied to her to not be jealous and to get over me and that I told her the full story already so not to bother. Now I get a hard time from my current wl that when ever she sees girl 5 it becomes very awkward and that she is now hated by a girl from that moment on in the same apartment building
