My boyfriend and I (both 25 yrs old) have been together over 2 years ( Ive known him for about 5). Last night I found out he’s been talking to his ex. She’s been sending him messages saying she wants him back. And he’s entertaining her, texting back and saying “sadly I have a girlfriend so we can’t do anything.” I don’t think he has done anything but just the fact that he’s texting her is pissing me off. In the messages, apparently they were supposed to meet up for casual sex but he didnt want her to get emotionally attached so he didn’t go. Then when I confronted the situation last night I told him to either explain the situation so I wouldnt make assumptions or to leave. He decided to walk out the door....

He texted me this morning “have a good day at work” but I didn’t go in today. I believe he’s at his moms house right now. I just dont know what to do at this point. Should I ask him to come over so we can talk it out or should I just end things?
