I've been living together with my current gf for about seven years now, but about a month ago, she met this guy at work and she started receiving text messages from him. I checked her phone and to my surprise that she has been texting him also and i overheard her saying to one of her friends that she is starting to fall for this guy. From then on everything I do annoys her while this guy would text her any time and she becomes excited when he does. I asked her a few times if she wants to break up, but she wouldn't give a straight answer only that she is still groing up. She also started hiding her phone so that i wouldnt be able to read his text messages. I also found out that they had been on a couple of dates and she never told me about them. I had to find out from a friend who saw her with another guy. what are my options please anyone? am I wasting my time?
