Am I wrong?? What can i do??

I’ve been with my boyfriend for almost 3 years, we’ve been ttc for two months. This month I’m actually 22 days late but keep getting BFN whenever I test. This last week literally everything my boyfriend says is annoying me to the point where I just don’t want to talk or see him. For the last couple of months I’ve been talking *as friends* to a mutual friend of ours from high school but I’ve caught myself catching feelings for him... I had stopped talking to him for a while for this same reason but whenever I feel upset he’s always there for me and this last week when I was feeling suicidal he was there for me, I couldn’t help it and I’ve gotten a case of deep feels for him... what do I do??
