I've been with my partner for nearly 4 years. We have a good relationship and I know we're right for each other.
They had some difficulties in their past and for many years (before we met) have been part of a support group where they can talk about any feelings that brings up, or just listen to others.
From very early on in our relationship I made clear to them that they could talk about anything they wanted with me. I also said that I realized there may be some things they wouldn't initially want to talk about with me, but that I would be here whenever they decided they wanted to. They thanked me and said they appreciated my stance.
It's now 4 years later and I'm still in a situation where they mention to me some feelings or memories had been brought up by something, I ask if they would like to talk it through with me and they say no. They'll talk about it with their group instead. It seems to have come up a little more often in the last few months and I can't deny it does hurt a bit. I've not said anything directly and I'm not sure if I should. I'm glad they're getting so much from their support group and would never dream of asking them to step away from that.
I really just want to ask them when (if ever) I'm going to be someone they feel they can talk about anything with. I got to that position with them long ago. Should I press this issue (and if so how), or do I just resign myself to the fact that there are some things they will probably never want to talk to me about?
