Relationship Advice?

I’ve been struggling lately. I really do love my boyfriend and we haven’t even really had a serious argument the four years we have been together. A few weeks ago, we had a dumb quarrel when we were facetiming. It was just about the possibility of hanging out the next day… It was a pretty complicated position to be put in because I had so much stuff going on. Though, he seemed persistent to see me the next day. I semi-jokingly made a quip about “You’ll survive a week without seeing me, I think we should stick to our original plan and see eachother next weekend.” Then he replied with a very hurtful comment. He retorted with a mumbled “Yeah, I can survive my whole life…” At first I thought I just misunderstood him, I didn’t really want to automatically assume he was saying something hurtful. So I said in reply “I don’t really know if you meant it the way I took it, but I’m probably taking that sentence the wrong way.” He nodded and simply said “I know.” Then I went silent for a good five minutes, I wasn’t expecting him to say anything like that to me in a million years… He was always so respectful and sweet. I figured he was going through some rough spot in his life at the moment, but it didn’t help the fact it still really hurt to hear him say he could survive his whole life without me. He later sincerely apologized, he was even getting emotional about it saying that he shouldn’t have said that to me. I know this is probably just some bump in the road, it’s only a minor thing… I’ve mostly forgiven him but it still hurts to think about. It made me rethink our relationship, though it made the most sense to keep going. But I’m having second thoughts again. I’ve been having anxiety around his parents due to his father constantly hounding me with questions about my plan for my life and how much money I will make in the future… He has a great relationship with his parents too. (Which obviously would effect me) The main thing is that my boyfriend doesn’t seem to support me going into a education major… Whenever I bring it up the topic of him not understanding why teachers need a ‘major to teach someone 1+1’ comes up. Another popular topic is how low the income is for the teachers in my state… His dad never said anything negative but seems to ask me a lot about money whenever someone brings up my major. So my question is: Should I overlook this? I love my boyfriend, his sweet and responsible… Though these problems wander around my mind constantly. A little advice would be appreciated :) Thank you!
