i faced the same with my boyfriend. he is a wonderful person but after a few years (this was a long distance relationship) things got so bad that we have decided to split. he is the love of my life but that is it now.
see a therapist if she is willing.

yes, I have experienced that. There is almost no way to combat it if the person doesn't communicate well with you. I mean, you can try to be more attentive, look for signs in their actions, words, etc. but some really hide it well until they reach the boiling point and then let it out in full fashion. Then all you can do is react.

My suggestion would be to talk with this person. Let them know that you want to be able to work things out. You want them to be able to come to you when something is amiss, and that you want to work on having better communication for you both so to be more proactive in the relationship, then reactive.

It all starts with someone making the first step to talk, even if it has to come from you to set the stage.

good luck

I have had that problem for years, the difference my husband waits months to say something by that time i can't remember what he is talking about. And of course then I look like a lier. Can't tell you how to handle it cause I haven't been able to, but I can feel your anger I fell it to.
