Is putting a relationship on pause sometimes the best option despite feelings? I’m not experienced in love, I need advice?

I don't know how other people move through life and relationships so I’m asking this to see others’ opinions.
But this guy and I met months ago and we have mutual feelings for each other, even when we try to end it since it would be in our best interests because of where he’s at, we always come back around mutually. He is jobless, broke and just graduated starting to kickstart his career and he’s 30. So he feels like a failure but since he graduated in law he knows now is his only time to achieve his goals and be successful. He’s swamped with work and clients and has taken an internship abroad at the end of summer til next March. Although he has expressed to me he wishes he could continue with me and likes me, realistically he doesn’t think it’s possible right now. He said maybe down the line when he’s back home, but he doesn’t expect me to wait for him. I think he has low self esteem too and he doesn’t think I would wait or it’s a lot to ask. He’s had bad long distance relationship experiences before and doesn’t want to ruin something we have by attempting it either. So he says to avoid the mess we should leave it be for now.
Can anyone tell me if this all makes sense or is this just a case scenario if he’s not that into me? I’m not experienced in relationships so I have no idea. All I know is I have fallen for him.
