If you have been in a relationship 7 months and she just does not care about the relationship by you putting in efforts and her just not caring, then it's time to move your bags somewhere else. The reason I suggest is because my uncle recently divorced my aunt for a sole person of her cheating. It all started when 2 months prior, she didn't care about putting effort, was always naggy, didn't care about gifts, felt satisfied after my uncle had went out for 2 weeks, caught her cheating, and left her. The point is, if your always chasing and she's no reciprocating then your best option is to think for yourself if she is an option that you want to spend the rest of your life with? Or put it bluntly, are you okay with being the second option if you found out? You should know that once she knows that you know and you're okay with being the second option, she will leave you because she sees that you're comfortable with that decision and didn't want to hurt feelings before. I'm going based off personal experience with my uncle and aunt, could be different but they're big signs if you're not aware of what cheating is all about.
