I'm upset with my boyfriend because someone he used to hook up with texted him today
Do you know the girl that is texting him?
Yes, I've seen many pictures together.
You shouldn't be mad at him over something he has no control of. Understand that it's not his fault someone else texted him.
I don't understand why he would lie to me. I wanted to get over this jealousy phase and he just spreading it again.
He may have withheld information about because he was worried about your reaction. You two need to sit down and talk this over.
