Search Results: how to tell if someone is interested

2 years ago I gave an acquaintance my phone number, which is something I already hate doing. For most calls he would either end the phone call after a few minutes to "see why 'she' is calling" or talk with people off the phone.

Important Side Note: He told me about a planned group outing with our mutuals and "someone else." I found out through social media that "someone else" was a girl I've seen around but never really spoke to. I suspect that "she" is the person he would cut our phone calls short to talk to. I thought it was really weird of him to hide that she was on the trip, especially since I recognized her; I literally don't care who he dates because I was only platonically interested in him at best. This incident, however, made me feel like being his friend was not a good idea.

One day, I told him that he should delete my number if he calls me again and exhibits poor phone etiquette. Like clockwork, the next time he called, he cut the call short because he couldn't understand why "she" was calling him. I told him to never call me again and promptly stopped answering calls and texts.

As time went on, he and "she" developed a relationship that he posted about. "She" recently had his baby. I was hanging out with some mutuals and he came around. I acknowledged him but cut my time short because I didn't want to spoil the mood. Since then he has been watching my social media stories, DMing me, and calling me. I have not responded.

A part of me feels bad for my lack of communication with him, but I also don't understand WHY he's trying to talk to me. A part of me wants to ask him why he's trying so hard to engage me when he should be tending to his girlfriend and his baby, and a part of me wonders if he's just trying to work on being friends. I personally do not trust this man and would rather he would accept that I told him to leave me alone 2 years ago than pursue a friendship.

WDYT?
