Friends with benefits?? Advice please!!

Hey guys, looking for some advice really! So there's this guy at work who I have liked since starting, since then I've seen another bloke who's in a long distance relationship, he basically wanted it so I stupidly went round his & we ended up almost having sex but he freaked out due to him cheating and people finding out. (I realise I'm in the wrong I shouldn't have seen a man who's with someone but it's besides my point.) The guy who I like found out, he wasn't bothered by it at all, we spoke alot after that and I ended up telling him I liked him, and he said he liked me too and that it will be good to carry on talking. I also made it clear to him that what happened with the previous guy was a massive mistake and I said that I'd take a step back and not see anyone or have any sexual partners for a while. Adam (the guy I like) said he respected me for that which was nice. Shortly after Adam told me that he didnt feel the same way I did, he still loved his ex and that he's sorry he told me otherwise and leading me on..

After a few months went by we carried on speaking more and more, I told him I still liked him and he said that we should talk about it! I was super worried as I don't like confronting people about my feelings so we never did talk about it outside of work. He did say if I'm looking for a relationship that wouldn't happen due to him not being able to care for himself enough, let alone another person. I understood.

To drag this on even more we are now talking again... ugh I have patients...

We have spoken so much, met outside of work & spoken about alot of private stuff, all my work friends just say keep going he will eventually realise what he has!

Last night we were talking about sex, I sort of implied that we should do it and he was like yeah definitely!

Sooooooo if I did it would be like a friends with benefits sort of thing. I like him, I don't think we could ever be together but should I go for it!? 😬 Try it once and if I feel hurt that he doesn't feel exactly the same way I do, not to go back!?

I've never had this situation before,. it's super complcated but I know for a fact he wouldn't ever try to fuck me over or hurt me. He's a lovely guy but I'm worried I'll be the one who's hurt due to my actions!!

Well done if you've red all this, I'm sorry for the essay, but advice would be appreciated sooooo much!!!

Thank you x
