Should I believe him or Should I wait?

So I've known this guy for 2 years. 
We've started catching feeling for about 7 months now. We had dinner one night and just let it all out , we told eachother how we felt and it's crazy because in all honesty he seemed to be filled with more feelings than I could imagine. He said I make him happy, he can't stop thinking about me, and that he couldn't tell if I would've felt the same way since his situation is him currently going through divorce. I've always had a little something for him from the start but I always hold back because I'm not the type to show feelings right of the bat AND I knew he was married but with issues. He calls and texts me EVERYDAY. But see here is the catch. When he visits his little boy during the weekend he rarely calls or texts. His excuse is always "baby I'm really trying to get this divorce clean and with no problems" so if his ex wife finds out he has a honey will it cause issues in the whole process of divorce? He repeatively reminds me, his kids and I are the most important thing to him. I'm trying to be strong and support him but I catch myself feeling so doubtfully. 
Do you know someone who went through the same thing?
