Single parent and SO meeting kids

So I’m looking for personal experience mainly but feel free to give hypotheticals also. I am a single mother, I essentially have been since my first son was born 4.5 years ago. I dated my second sons dad for a mere 3 months broke up then found out we had gotten pregnant and we never got back together.

I tried to dabble in dating when my son was around 5 months, I wasn’t ready and was going through it. I’ve since been in a year and a half (give or take) of therapy working through a LOT working on myself making a better life for the boys etc and didn’t feel called to dating until a few months ago so i tried to but then things flared up again with custody for my youngest and I felt like I just didn’t have the capacity to explore a relationship.

I deleted the app (hinge) and at that point I had been on two dates with two different men, one dropped off the other was still interested so I was honest with where I was and that I could only do a friendship and if it grew from there great if not that had to be ok with him he was all for it we’ve been talking daily on an in depth level ever since. I’ve background checked him and he’s a total nerd but that’s about it 😂 works for the city and he even is in therapy of his own working through some childhood traumas very similar to mine. We have done nothing physical, he actually tried to kiss me the first date I said I wasn’t comfortable with that and he absolutely respected it and didn’t get shitty for feeling embarrassed.

He has been extremely respectful, patient, engaged, etc. it is hard to try and plan time with him and over the last few months we’ve seen each other once a month. Our time together is always so amazing but not in an infatuated unrealistic way, it feels and seems genuinely real. I’ve been through a LOT (assaults abuse etc) so I feel I’m finally letting myself take the time to truly evaluate this person as a partner.

I guess my question is I want to keep getting to know this person who really seems genuine but don’t want to be reckless in any way. I don’t know when is ok to casually introduce him to my boys (as in a friend in a non intimate settling which I do have guy friends so it’s not foreign to them) either at the park or he has offered to help put together our homeschool activities, or something of that sort with obviously no PDA because we don’t even do anything in private anyway at this point. Anyone have insight?

**eta: yes we have talked about this being means for a serious relationship that’s the goal here just continuing to get to know each other and have both agreed on no sex until marriage because we don’t want to become blinded by infatuation. I’m not asking because I plan to soon, but because this is the first potential relationship I’ve had in years and I don’t know what that timeline looks like.
