My boyfriend told a girl that he didn’t have a girlfriend, that we were on a break (when we weren’t) and that it was ‘complicated’. How should I handle this situation?

You could wait until you can find the right moment and try to be honest with him and ask him if everything is ok in the relationship . Depending on what he replies you can make a decision about how secure you feel the relationship is. Honesty is always the best way forward even if your partner hasn’t been honest with you. Hopefully this will give you some insight into what kind of a person you are with . Also I suppose you should think about what reason your friend told you this as it could be untrue and it could be your friend who is not be straight with you for some reason ?

Personally, if I was in this situation he would no longer be my boyfriend and the situation would end there. I see that as a major sign of infidelity and that is something I find unforgivable within a relationship. Sometimes it can be hard to look at the facts straight and see the intentions behind his actions, and I couldn’t see it any other way then him attempting to be unfaithful. I would consider the situation as if he has cheated because that’s what his intentions seemed to show, would you be able to forgive him physically cheating and look pasting or Would it be simply unforgivable to you? I think that is what you need to ask before you make the desicon.

This must be very hard for you to hear, but the only way to deal with this is to ask him why he did that and he doesn't gives an answer that you can believe, accept and trust, LEAVE HIM! He is not worth your time, attention and love. If he can deny being in an relationship that means he doesn't respect you and this relationship, it's non existing for him and when he doesn't accept this publicly, he is not a man who can be trusted, it's better to get rid for once and for all like removing a bandage quickly.
