Go to uni.
If it's meant to be and he's right for you, the relationship will last even if you go to university. If he's not and it doesn't, then you haven't thrown away all your dreams and hard work for him.
It also sounds like the place he lives isn't somewhere you want to live - and I think you're right to be concerned. High unemployment rates don't usually translate to a good standard of living and you'll be moving away from familiar surroundings, possibly even family and friends.
If he truly cares for you, he'll support you following your dreams. You don't *have* to give up the relationship to go to uni - it might be harder, but there are definitely ways to make long distance relationships work, and people do it all the time. I know several people in successful long distance relationships. If he tries to guilt trip you into giving up everything you know and have worked for to come with him without consideration of what going to uni would mean for you, run. Run far away. That's a massive and dangerous red flag. (and even people who seem to be amazing for the first few months can turn abusive and controlling very quickly - speaking from experience, unfortunately). I don't want to say that your boyfriend will, because I don't know him at all, but please keep it in mind. If you move somewhere where you're isolated and dependent on him because you can't find a job, that's a completely different situation to being at home, working, surrounded by friends and family and with plans for the future.
