Most Helpful Girl
Yikes, that's got to be a painful situation.
What he means is just that, he needs something from a relationship that he's not getting from you. Now he is the one who has to express to you what that need is. I cannot speculate on what your relationship is like, how you two are around each other, what your interactions are like. But he has turned to another woman because he is getting from her what he isn't getting from you. I don't condone this behavior because it is disrespectful to you and your committed relationship. Instead of turning to another woman, he should talk to you about where your relationship is lacking and work through it. Not that it can be worked through in every case. Some cases people get married when they're not a good match for each other and no amount of work will fix it. But every case is different. Personally I'd say if he doesn't respect you enough to come to you first to work out issues, and goes to another women to get his needs met outside of the marriage, then he's probably not worthy of your commitment.
