I'm terrible at communicating in relationships. I hate arguing and confrontation (my parents modelled this really badly for me) and I'm not at all assertive, so I avoid arguments or raising any issues that are troubling me at all costs. It feels like there's never a right time to say things that are on my mind and I just can't seem to find the words, which means that I bottle things up. I'm talking little things like asking my partner for more help with washing/cleaning etc as well as bigger things such as issues in our relationship.
So I'm wondering what does a healthy relationship look like in terms of communication. Do you have a particular time when you raise issues (like a weekly sort of family meeting) or is it just as and when things crop up? If it's as and when, how would you do it and what sort of words do you use to bring things up? (Because I'm a bottle-things-up kind of person, it feels really awkward and like I'm blurting things out.)
As I said, I have no frame of reference for this sort of stuff and would really appreciate any advice or hand holding. Thanks!
