Should I give him a second chance?

My boyfriend and I recently went on a holiday, during which we got into a serious argument. It got so bad that he simply left me at the hotel and went away. I was shocked because I have never been treated this way ever before, by anyone. I returned from the place by myself and went home without telling anyone about it because they would be too horrified. He began calling and texting a day after I returned, apologising constantly and swearing never to do anything like that again. I didn’t respond for a day or two, because I wanted to think about what had happened, and then told him that I wanted to end this relationship. He took it very badly, saying he knew he had done a horrible thing and asking for a second chance. I don’t want to give him that chance because I don’t think anything can justify his behaviour. My family and friends want to know why this ended, and I tell them it was a private reason, but they think he’s amazing and want me to reconsider. Was I wrong to end it?
Your family and friends don’t know what happened, so they aren’t in a position to comment. You were treated badly and disrespected. If you can’t forgive him, you have every right not to. This may feel like a hard decision to make, but you have made it based upon what you think is right and wrong. If he acted in a way that went against all your expectations, he should learn to live with his mistake. Time will address any lingering doubts you may have. Stick to what you think is right for you.

How can I convince my boyfriend to spend more time with me on weekends? He says he also has to meet a lot of other friends.
Look at this from his perspective, but also tell him what your expectations are and ask him to work out a schedule that seems fair. This shouldn’t be difficult.
