You are worried about ruining this 2nd chance. He didn't give you a 2nd chance; you gave him a 2nd chance. He has given you very good reason to suspect that he is not truly in love with you. It has nothing to do with the girl who came on to him. It has to do with his lack of feeling for you.

This guy is not looking to settle down. He's over 30 years old and he's been seeing you for 5 years . . . . and he had to leave you to have space and think. I don't think you can possibly feel trustful of his love, regardless of even if he is not texting or calling anyone else. It's him who would have to be very persuasive to convince you.

I don't believe everything was fine between you two before he took that break to clear his head. In your heart, you know that too. You are very much in love, and he is not. That's what your gut is telling you, and it's an awful thing to feel. I'm sorry you're going through this hurt. I believe you are very hurt that this relationship is not where you hoped it would be. You probably have been making the best of a bad situation for a long time. Finally, he tested you in a cruel way. This is not the behavior of a man in love.

You may have to face that this is not a relationship that you really want. Again, it has nothing to do with other women. It has to do with him not needing you anywhere as much as you need him. That's an awful tough situation to be in.
