I understand your confliction - a lot of us moms in our 40s I think when we start dating face the same.
There are loads of blokes that just want a casual shag and make no effort. So we dump and block. Then you find one who seems interested in you as a genuine person, not just for sex, and you think, well hello!
But all too often those ones want too much, too soon. They want to parachute us into full time commitment, when we aren't ready for that at all (or even if we are, we want to be choosy about who we commit to, quite rightly).
It's absolutely valid to dump and block a guy for wanting too much too soon, too. I have done the same. And I felt bad because it was after the second date and I had shagged him (which was lovely, but....). He clearly saw us as an item at that point, and I just didn't.
You are fully entitled to go with your gut at this point. Just send a polite message saying he isn't the one for you. You are not ready for a relationship, whatever. Then block without guilt.
You owe him nothing. And there ARE men out there who can offer what you maybe want, if that is fun and friendship and romance without the whole full on RELATIONSHIP straight away deal.....
They just take a bit of finding. I have found one, finally. And so can you.
Good luck! And stay true to yourself. You didn't escape from what you went through before, to ever let a guy make you feel unhappy or trapped again.
You owe it to yourself not to. So don't
