Why some of men don't apologize? My bf said he'd call but didn't. The next day, he IMed "I missed you last night" and didn't mention "Sorry." How can I let him know that hearing "sorry" is important to me? It's the issue since we started dating 4 yrs ago.

say what you mean with a smile on your face and you will get your point across without offending him cuz he won't know if your serious or not but you will make him think

How can you let him know? TELL HIM!

Do try not to be critical, but talk about how you feel. Actually, I think you did a pretty good job with your question.

this is a tricky one. If he felt remorse for blowing you off, he woukld have apologized all by himself. So, your dilemma is "how do i get him to care about my feelings?" The answer is, YOU DONT!

You've stayed in the relationship for four years, and you say this problem has been an issue the entire time, right?

You've accepted the behavior for four years (staying in the relationship IS accepting the behavior), so to complain now and/or expect him to change is ridiculous. You've shown him how far he can go, how much you'll put up with, and he's gotten comfortable with the situation.

Some women complain that most men are dishonest; isn't it a little dishonest of you to take something for four years while harboring negativity about him?

You have every right to bring it up, but the ultimate decision is yours, not his. Either keep taking it and never mention it again, or get out. Simple as that. In your next relationship, if you don't like something, don't keep taking it for four years, not even for four months or four weeks.

tell him just because it is implied doesnt mean that you dont need to hear it sometimes. i think the same goes for "i love you". people in a relationship know they love each other but sometimes its nice to hear the words also.
