Blowup with fiance reveals true status of relationship

DEAR ABBY: I’ve been with my boyfriend for a year and a half. We broke up for a while, but got back together and have been doing great, and we got engaged six months ago. Last week, we had a huge fight, where all my bottled-up resentment came out. I have tried to communicate my needs, but while he changes briefly, things always revert back to the same.
