Wanting to stay single or dating someone from hs who has a kid?

HES A SUPER SWEET GENTLEMEN.

So ive been single by choice for over a year.

A week or so ago someone from HS (5 years ago) started hitting me up because he's going through a divorce, she cheated. They have a kid. We're only 22. (Its been headed that direction for a while but reality is setting in kinda thing)

Well im letting him stay at my place till he figures out his situation. But he really likes me and wants to date. Hes only ever been with 1 person. And i personally feel like that's not enough life experince to settle down.

...

This is how i feel:

1.) Im not even sure if im ready to settle down like that!

2.) Plus he has a kid, thats a big commitment.

3.) We havnt talked since high school so how does he even know if he really likes me like that?? We've changed since then.

4.) I just had all of this dropped in my lap not to long ago, its a lot to take in Idek how i feel.

5.) He's SO nice, but its sort of the "nice guys finish last" situation. Like typically 'girls' only wanna date bad guys. I feel this is one of the big factors as to why im iffy.

...he knows im iffy about dating. He knows I like to be single. Hes aware of how i feel. Both being 100% transparent.

What do you guys think about everything. Advice ? What would you do ?
