extremely nice guy but no oomph

Michelle
After 2 abusive marriages, 1 mentally and the other physically, I met a nice guy but he didn't really have time for me. I fell in love wit him and couldn't wait to see him, talk to him or receive a text from him 
It felt magical but over a period of time the relationship fell apart
I had someone but I was alone
2 years on and I have met up with a guy I used to go to school with 
He is the nicest guy ever. So sweet, always texting. But he has older children and needs to be dad to one of them. I completely understand as I'm a mother of 3 myself 
There is a lot of time apart. Which I seem to be used to in a relationship with 2 of my exes working away a lot
I dont think this guy could do me any wrong and I'd never want to hurt him. It is still really new. 4 months approximately. I can say I love him but I'm not in love if that makes sense.  There is no oomph. 
I'm wondering if in time of spending more time with him I'll get that or if there will never be anything more then respect 
Do I wait it out?  I think he is in love with me
And maybe I should just be happy that I have finally found a really nice man 
What do you all think?  Too afraid to mention this to girlfriends as I don't want it to get back
