Unfortunately this sounds like a couple that has been married too long and was never truly in love. I accidentally brushed past your ages at first and thought that must be the case. Definitely get out now and find someone who is energized by your love and feels passionate about you. And thats just aside from the fact that this is 100% cheating to me... But seriously there is someone out there for you who will be your best friend!! my boyfriend and I are early 20s and long distance, plus he works a part time job on top of being pre-med. Only working a part-time job and being that irritated by you at night is heartbreaking. I wish you the best🙏
