He knows I meeting other guys. I actually want like a casual relationship. So, if it does happen, I will have to break things off. I wont cheat.
The reason it might get complicated because I'm helping him financially.
From the little you said, it sounds like he doesn't want to face the idea of you leaving him. Perhaps you could look a little deeper to see why you want to leave? Is the romance gone? (It can most likely be revived.)
I don't have a lot to say (having two failures under my belt) but I was hoping if I replied it would bump your post and someone who has really good advice could help you.
