When to cut it off with an INFJ

I’ve noticed a pattern with some INFJ friends where they were unhappy in their romantic relationships but struggled to fully admit it to themselves or to others. As a result, they stayed in those relationships longer than they felt was necessary, at least based on what they later expressed.

Now that I’m dating an INFJ myself, I sometimes wonder how to tell whether my partner genuinely wants to continue the relationship, or whether I might be investing time in something that isn’t truly aligned. He doesn’t hide the fact that we have certain issues but jr doesn’t seem like conversations go anywhere given that we see things so differently. I asked him if nothing changes if he would be okay spending forever together and he’s certain that he sees things changing since we’ve both grown so much over the last two years. I’m not necessarily so sure since I think we have grown as much as we possibly can and will just have to either live with certain differences or move on. We generally have a good relationship but I get scared seeing this pattern in my INFJ friends.
