Hmmmmm... Your boyfriend shouldn't hold you back with his jealousy, he should understand that there's a reason you're doing this. If you explain to him repeatedly and he keeps on projecting that same fear on your relationship, I believe you should let him go and focus on yourself. He's a student and your parents are not helping out, what does he want you to do? Put it to him that it's his choice to stay or to leave. Don't let the fact that you love him be your own weakness, you are meant to go high and beyond so don't let any guy's insecurity hold you back. Talk to him again, let him know that if you should leave that job and you are not able to cater for yourself, will he be okay with that? Ask him questions so you can know what is in his head, it might not only be his insecurities, selfishness could be playing another major role in this. I hope this helps in solving your problem.

Have you tried to sit him down and ask him why he's doing like that? If you haven't done that, ill advise you do so as soon as he gets back. Tell him what you have noticed and how you feel about it, his response will determine what you will do. If he sounds nonchalant and he's not giving you any reasonable excuse whatsoever then you will know that you're dating yourself. In all, make the best decision for yourself and think of your future while doing that
