Fwb vs relationship vs nothing?

I've been friends with benefits with a guy for around 4 months, I lost my virginity to him. We had kind of relationship intentions thing for 3-4 weeks, at the beginning then we decided to stay fwb. I lowkey fell for him but I knew my position in his life so I kinda got over him. We stopped our fwb when he got a girlfriend, it lasted around 6 weeks and 2 days ago he texted me saying "I still have your scarf, girlfriend went mental at me and didn't let me see you to give it back 😂 not with her anymore, I'll give it to you whenever" well we started talking and of course went to a possible hook up again.

Meanwhile, in 8th of March I started talking to a guy who lives 2h away, he really likes me, he's actually so into it and is so serious about us, he's already making future plans like "If we're still together in a few years, would you move in with me?" He's actually so nice to me, he also wants to meet my parents and wants me to meet his. But the problem is, I don't quite like him in that way and now that my fwb and I started talking again, I feel like my feelings for him are coming back.

I'm actually feeling like shit, I have to choose between a guy who would probably never want something serious with me that I like and a really nice guy, who wants something serious with me, that I don't like in that way. I don't wanna hurt him, but I know I would. And if I continue and tell him after a while, that's just gonna hurt him more. I can't even let him kiss me because I just feel like a twat for what I'm doing. 

Can someone give me an advice, please? I have no idea how to sort this out, I thought I was over my fwb but apparently I'm not
