keep in mind the cause or reason for his behavior is on him, there is nothing that you can do to change those things about him. You do have to decide whether he's worth investing in and expecting anything long term.

Thing is, I am of the mind that one should go into a relationship and expect it to be wysiwyg so to speak. yes, things change, people change but what I mean is we should go into a relationship and what we have now should be acceptable if we are to decide to stay with the person. Regardless of what happens in the unknown future. Getting started in a relationship and deciding to commit when you're in a relationship where you want some things to change about the other person, is just asking for pain and suffering and is really not fair to the other person.

Figure out if you can accept how he is now, the pushing, pulling, on again, off again, relationship... if you can see yourself another year down the road going through this with him and he's worth going through all that, hang onto him. Otherwise, well, you know what I'm saying.

Thing is looking at your post, at the most what I see you saying somewhat positive is that he is hard working with regards to his MMA training. Ask yourself, what else is it that makes him so desirable, and are those things enough, to make the erratic nature of the relationship worth it?
