When do I leave if he doesn’t want to commit?

I’ve been with the same guy for four years, we’ve had our ups and downs and he has 2 kids I have one from separate relationships, he was married I wasn’t. He says he’s to scared to be in to a relationship because of his past and his kids are demanding but I want more out of the relationship and have told him multiple times. When do I call it quits? He’s still “technically” married and seeing a councillor to overcome these issues but we have nothing to show from our four years together. We did live together but he chose to move out and buy a house for himself and his kids (not including me) so I purchased my own house, we now live apart and I want to be with him but I don’t want this relationship I’m currently in. Please help.

Technically married means they seperated 9 years ago but are not divorced.
