Common to start fighting with Partner for two months off and on?

We have never really caught before up until my shift change being off schedule through us off we made it work but had communication or our conflicts resolution wouldn’t be as effective the last month. First month we were working different schedules and staying at his folks place during the holidays he was off I had to work. He recommended couples therapy.
We have only been dating 1 1/2 years. Living together 6 months. I lot of topics have been serious ones regarding a family adopt or biological making the official choice we had discussions before, making a verbal non legal agreement outlining what we’d want or need to proceed if we purchase a house and ever split, and and financial scenarios. He is traditional liking to support financially and makes more. I was raised independent, and make less (before moving in we agreed to just rent being proportional I have more financial obligations then him (support my parents)). This is our first serious relationship and never had these conversations with anyone before and are learning to grow together in areas he got no clue on.

Is it wise to go to therapy?
