Worried about hurting FWB's feelings

[Mamaka]

I am 4 months into a painful and messy separation - my marriage was also painful and messy so I'm happy to be out of it.
I've somehow managed to get into a kind of FWB situation with a really lovely guy who I met by chance (I wasn't trying to meet someone) about 8 weeks ago. He is the total opposite of anyone I've been involved with before, very sweet and genuine, funny and affectionate, we have such a great time together. He's told me he's not seeing/sleeping with anyone else (not that I particularly care) and I've told him about my separation and that I don't want anything remotely more serious. The problem is I am sensing that he likes me a lot and I'm worried I'm going to end up letting him down. I really didn't anticipate having such a lovely time with this guy and us getting on so well (plus he has totally reawakened my dormant libido) and I get the feeling he is hoping that if he hangs around long enough I might change my mind about what I want.
Should I not worry about this? I've been honest with him so it's not really my problem is it...

If you're really not remotely invested then all you can do is be honest and make it clear you're not in this for a relationship. I had this and as he got more hopeful and needy I was increasingly turned off so it fizzled out because he made me feel quite claustrophobic.

Your comms might not be helping either. If you're texting daily, sending goodnights and good mornings then this really muddies the FWB waters and helps attachment. If this is happening then maybe let him know you're worried that the frequent comms is muddying the waters so you're going to back off on that. Just guessing so I could be way off base!

We do text daily and he also calls me every couple of days, which I admit I really enjoy because he's hilarious and I feel like I didn't laugh during my entire marriage!
Good point about this level of communication. I'm seeing him in an hour, not sure how to go about putting across what I'm thinking?

Bumping quickly before I meet him!

If I were you I'd not worry.
He knows you are not even divorced yet. And you already told him - upfront - that you are not looking for anything serious.

Don't double guess what is in his head. He is an adult and can take care of himself.

If you are having a a good time - good for you!!!!! After what I can only assume a few miserable years - you've earned it.

Why not relax and enjoy yourself ...

Just go with the flow . No need to set barriers or limitations you're both adults.

You clearly enjoy this man's company. He enjoys yours. You are not in a position to commit to anything serious, as not even divorced yet. He is an adult and realises it.

I honestly don't see why you cannot keep enjoying each other and cross that bridge when you come to it. You are nowhere near that bridge yet anyway, so do relax and live in the present!

You are all right, I need to stop worrying (I do have a history of taking responsibility for other people's feelings!)
We had such a lovely night tonight and he did start to tell me how much he likes me, I asked him not to and he was fine with that.
So...relax and enjoy.
