Today something happened with ? U should listen whole story

Pata hai aaj kya hua? I (22F) am in a relationship with my classmate (22M). We have been together for ___ months. Before relationship, he had a crush on me. Slowly we became close. I am talkative and he is an introvert, but he listens to me a lot. When I took leave for a week, before going I told him “you will miss me.” And he actually did. He called me and said “aaj ka din suna tha tere bina.” He even told his close friends that his day didn’t feel good without me. Earlier I used to see him acting happy, but after coming into relationship he looks genuinely happy. After relationship, he loves me a lot 😭 If I talk about trauma, he holds my hand and calms me. He holds my hand while crossing the road. Because of me he left smoking. He kisses my forehead before going home. He keeps my clip with him and my photo in his wallet. He has no ego, he says sorry first. We don’t fight much. I am his first girlfriend. He is emotionally a little broken, and my past is also not perfect. He says “2 broken people make a beautiful home.” But the issue is this — I struggle with adjusting. I feel like I am adjusting now because I have no option, but what about future? The main problem: he is not serious about his career right now. We are both in biotech. I want to continue in this field seriously, but he wants to change fields. He says he loves me and if I leave, he will become capable and prove himself. Sometimes he even says things like “even if divorce happens, we will marry again” which feels immature to me. I feel he is not serious about life yet. He says the “push” hasn’t come yet. He is a good person, very loving and caring. But I am confused — is love enough? Is it worth staying if career mindset doesn’t match? Is he the right person? Or am I ignoring a red flag? Please help.
