Boyfriend sharing a hotel room with female coworker alone in Vegas for 3 days.

Anonymous
My boyfriend who I've been with for over a year planned a 3 day Las Vegas vacation trip with a female coworker.

1) Both of them planned it together. afterward, they asked other coworkers to join in but none were sure of going, so it's really only going to be the 2 of them. He made it sound like it was a coworker trip. But why plan a coworker trip when really only the 2 of them are able to go?

2) He did invite me. However, it falls on my sister's birthday and there is no way of me going.

3) Something was brewing inside me to ask if they were sharing a hotel room. He said yes. I told him that it was inappropriate and he said that they're just friends and he's going on the trip no matter what.

4) He also sees nothing wrong with grinding with other girls in the club whether they are close friends or some random chick. I also have seen a picture of him holding hands with another girl who he claims to be touchy when she's drunk. Yet he allowed it anyway.

5) I forgave him for those instances because I only found out afterward. Now I can actually do something about this situation before it happens but as stated earlier he's going no matter what.

6) He's also never the first one to say sorry or reach out. I broke up with him and hung up the phone. It's been almost a week and he still hasn't called or texted.

7) He's a Sagittarius.

8) I really do love him. Should I try to get him back aside from making myself look pathetic? Or let him go, he's the pathetic one?
