I lost interest in a guy because he stopped texting as much. This is my best friend. Is this fair of me?

So, kind of a weird back story. Been in love with my guy friend for 3 years. We basically professed our love for each other, but he moved and we were unable to be with each other. We each moved on and had other relationships etc.

Recently, we started talking again. I’ve now visited him twice in 2 months. We were both on the same page, he said we obviously liked each other etc. and should figure things out. At the time, I expressed I liked him and we should try again. He agreed. He would constantly check on me, send me memes, call me, send me videos etc and FaceTime. We were intimate before he moved and started being intimate again. Everything was fine.

However, since I’ve returned from seeing him again the second time (were on opposite regions, north and south), he’s just been super weird. Only been responding to texts once every like 24-48 hours. Just kind of laughs or blows things off. Doesn’t respond properly to anything I say. Lucky if I hear from him. He’s now stopped sending “goodnight“ and just doesn’t even respond anymore at night. It’s been about 2 weeks of this. For example, he’s going to a concert tonight, one we both loved. He texted me this morning about it, then when I asked for details just blew me off. Haven’t heard anything in 12 hours

He also called me his friend twice on the trip, which was weird. In front of people too. I brought up a relationship before the trip and he agreed, but didn’t speak about it once while I visited. I was waiting till the time was right but he never said anything either.

I’m just distraught bc how could this guy go from basically plans to marry me and being my best friend, to acting weird within a week? It makes me cry, as I’ve known him for years and poured my heart out so I feel stupid. he’s never acted like this so I feel like a dumbass. I seriously would have married this guy.

what’s goin on? thanks in advance guys
