I've caught my boyfriend texting other girls before, but we got through it. We've been together for 5 years now. He was honest with me. He said he was only curious. I learned how to control my emotions and everything has been great lately. It seems like she's just throwing everything away now. This upsets me for you. You realized you made a mistake and we all make mistakes. It's hard to give advice since she seems like she doesn't want to work it out.

College life can change some people. I know of someone who had a great relationship. They lived together, her daughter from another guy basically thought of them as a dad... she wanted to go to college and he actually helped paid for her to start going. That's when it all changed. She ended up leaving him for a girl.
