Is this a 7 year itch?

Me (25F) and my partner (27M) have been together nearly 7 years. I need advice is this relationship is right for me or not or if I just have the 7 year itch? My bf if very loving but terrible at communication. I am very open and I think I am able to emphasise and see people’s pov. I don’t think he does and its like bashing my head against a wall in an argument at times. I love him I do and I can see myself having kids with him but at the same time there are deeper issues there particularly around alcohol. Sometimes I think about how if I won money I would buy my own house and live myself. If I left I would have to move back in with my parents where my dad also has issues around alcohol and it feels like a step back as I moved out with my partner at 19. We are looking to buy a house which is why I think the doubt has creeped in potentially. I don’t know what to do because I love him but sometimes feel its not enough. I haven’t been in a relationship before him and have nothing to compare to so is this normal? Does it pass? Or is this a bigger issue?

Tl; DR: can imagine a future with my bf but at the same time confused and feel I could live on my own. Bf is loving but has bad communication which is an issues. No past relationship to compare so don’t know if its normal. Is it just a 7 year itch?
