My boyfriend told me he hooked up with someone else when we were on a break.

That is awful to hear. For many, breaks can mean different things, e.g we are still together but we are having space a part, or we are having a short break up. Perhaps this wasn't clear for your boyfriend? Talk to him, see what he thought a break meant. Did the hook up mean something to him? Why did he do it? Get more information for you to be able to make an informed decision on your relationship

first question is how do you feel about him hooking up with someone while you were on break? next question is, are you willing to continue a relationship with someone knowing they may stray again or go back to the person they hooked up with while you were on break? most times when someone is into you, they stay loyal no matter if it's on break or during hard times in a relationship. you got to ask yourself if this is something you are okay with and be honest with yourself.

Wow. I will be mad. I will be happy that he was being honest with me by letting me know what happened during our time off from each other, but, this will mean that we will have to re-evaluate our relationship.

At least he is being honest talk it out with him and see if you still want to be together it might be hard but it will help you out just make sure your honest

You were on a break. Probably not the best idea for him to do that, but at least he was honest with you.

Tell him how you honestly feel about the situation. If you are on a break, realistically, it is ok since there was no current commitment with you, but it is ok to say that it hurt you. Ask if it meant anything and how he feels about it. Other than that, try to move on.

He told you he hooked up with someone else while on a break? Did you make sure that was true? He could have been lying.

Be understand yes it may hurt but he was probably seeing if he wanted to be with you and if you are still together clearly he did

At least he opened up to you about it now than never. This must be a shock to you and might upset you, so it's up to you to forgive, forget, and move on -- or decide to break up with him.

I kind of had this happen to me except he chose to be with her when I decide the break was permanent. After fighting I was given one month to get out. So I moved on and started talking to someone else which made him very jealous. So much that I even seen him texting her complaining. I went home to take care of my dad while my sister went on vacation. And the whole time I was gone he would continually asking me to take him back and the moment I said no he would immediately call me names. Anyways a week later we got a truck and went got my stuff and I never seen him again. Oh and I sold his engagement ring he gave me for 5 bucks
