Passing time on deployment

It might because I’m such a new military girlfriend but I met my boyfriend in September 2024 and we’ve been dating since then. He left for deployment in November. Before he left I didn’t think it would be this hard for me but we are both so new to this relationship and we have only been dating for 4 months and I have to wait 4 more months for him to come home. I genuinely don’t think this is for me, maybe if I knew him for longer and we were together for a couple years I would’ve mind waiting but this is so much for me. He only texts me once a day and he is an autistic and forgets to ask how I am and how my life is back home. Before he left things were great I just don’t know how this is even a relationship. Don’t get me wrong I love him so much but I don’t even know if it’s worth waiting… My mental health has gotten much much worse and I feel helpless this whole situation I don’t feel is helping, but if I do break up with him I know he’s gonna come home and I’ll want to see him anyway.
