bf help

So my bf and I 1 year and 4 months was today and for like the past 4 months I’ve been talking to this guy who I consider a close friend and my bf knows about this guy and is totally fine with me being his friend like he doesn’t think anything bad about him and stuff and my guy friend knows I’m dating my bf and for how long and he basically knows just about as much as I know about my bf and me as well we’ve been talking about school and relationships and everything else he’s a really nice guy and great person to talk to if I’m going through anything he lives in Brazil and I live in the US so it’s not like anything can happen between us but recently he told me he thinks he catching feeling for me and so he said we should stop talking Bc he knows I’m committed in my relationship and he doesn’t want to come in between what I have with my bf so we stopped talking until like 3 week ago and idk recently I’ve been like getting off the phone late with my bf and be getting ready to go to bed and then I’ll see his text (time difference so he texts me at random times in the middle of the night) and when he texts me i get so excited like more excited to see his texts then I am to see my bfs and idk why I know I don’t like him like he’s okay looking but I wouldn’t say he’s my type and I love my bf and like him a lot but recently idk why I’ve been feeling this way to my bestie it’s weird and if you gals could help me figure out what’s going on or why I feel this way it would be great
