rant/i need help or i'll cry probably

okay so there's this guy i used to be decently good friends with. he's homeschooled but we used to talk a ton at church/church events or whatever & we would text a lot. this went on from like july 2017 to new years basically. like our last texts we're wishing each other happy new year. abt two weeks ago,, he texted me after months of us not talking or texting!! i was v happy bc i've missed his friendship & stuff so ya woot. he's starting to text me again which makes me really happy BUT i used to have a crush on him bc we were friends duh & he's hot af. he didn't like me back tho (i wasn't surprised) but it was fine bc we were still friends so whatever i didn't really mind. SO now that we're (hopefully lol) gonna start talking more & becoming friends again,. how do i keep myself from catching feelings again?? bc now i'm being an idiot & thinking maybe he likes me bc he's been texting me first & is obviously trying to get us talking again. but idk i just don't wanna get hurt again. someone helppp
