By hot and heavy I meant it started fast and you are seeing each other daily, which is quite intense. You however didn’t get along and decided to cool off my seeing each other less. Typically healthy relationships start slow by seeing each other infrequently and then it progresses faster and get intense with time. Your seems to be going backwards as you now limit interactions .

I think he probably needs his space from fighting and bickering and that’s why he isn’t checking in. Maybe his understanding of space is different from yours. You aren’t on the same page about things. And constant fighting and arguments are concerning.

I am not sure why you are not worried about you two fighting and arguing but are worried about him not calling daily. I am not sure I am understanding this dynamics. If you fight and argue now, it’s likely not going to stop all of a sudden when you get married.
