Even when you have moved on and accepted that the relationship is over, seeing him with someone else is a different kind of challenge.

You may have accepted that that you are better off apart; that you two are not meant to be with one another, but then you see him with someone else and it crushes you. You get that heart-breaking, sinking feeling in your stomach.

No matter how long it has been, seeing him with someone else is not easy.

Your first instinct is to social-media-stalk her until your fingers fall off. It doesn’t matter if you find out she’s the prettiest girl in the entire world or a total troll - either result will make you feel no better than before. I promise you, verbally ripping the other girl to shreds to anyone who will listen will do you no good. You were in her position before, as I’m sure that there was someone before you, doing the same thing. Lowering yourself to trash talk and make mindless insults will not make you be the better person and it will not help you get over this any faster.

Seeing him with someone else makes you rethink your decision to end things with him in the first place. Did you make the right call? The answer is yes, you always made the right decision because if he was the right guy for you then there shouldn’t be room for that much doubt in the relationship. It was smart for the two of you to end your relationship and, as much as it hurts to see, you will be just fine.

Someday soon or later on in life, that will be you: being happy with someone else, the person that you will spend the rest of your life with.

You may even take seeing him with someone else as the time to wiggle yourself back into his life — don’t. You had your place in his heart for a time and now it is someone else's turn.

After replaying your relationship with him over and over again in your head, I hope that you come to the same conclusion that you came to when you ended your relationship with him: that you are not the girl he’s going to marry. You are not going to be the girl that he will be in love with for the rest of his life. You two do not have the life together that you earlier envisioned with him, but that is okay. You are a beautiful and strong woman who will find that relationship with someone else.
