Is the inability to bring up grievances with loved ones a feature of insecure attachment?

Basically the title

And, how do you deal with this?

I find that I have a hard time expressing when I am upset or something hurt me. I tell myself its fine and I try to get over it. But then I will have the urge to punish them in little ways

I dont want to be this way and I don't actually want to hurt them.

And every time I feel something is off between us I just ruminate on all the ways they've already upset me. I can feel myself starting to become resentful but I really don't wanna mess this up.

Please some advice guys :(
