<human>: Can you summarize the given text in a few sentences?

We met through work and started getting serious fairly quickly. After about 5 months we moved in with one another. Things were great, never argued but I didn't seem happy after about a yeah and a half. 

I broke up with her because I thought she was to selfish and couldn't compromise with anything. I thought it was the best decision I made, I was happy ready to move on. 

Two months go by with minimal talking and I agree for her to take me out for my birthday. It was like a complete switch in my mind after that night. I couldn't stop thinking about her and all I wanted was to get back together. 

We eventually get back together taking things slow. It's been about 3 months and things aren't looking great. I have been doing nothing but trying to make this relationship work and restoring her trust, taking her out to plays, dinners, movies, surprise gifts, listening to her and consoling her. All while getting little in return. 

I wanted to surprise her on Valentine's Day with a few things so we made plans to meet up after work, but she blew me off to get dinner with a friend and proceeded to get drunk without calling me after to tell me her plans. I explained my frustration and she felt really bad and had me come over the next day Where she had some gifts for me and a sorry note. 

However this passed weekend On Sunday I noticed a text conversation open on her computer from a random number where they have small talk and plans to meet for some drinks. She even texted him at 3am to meet up. They didn't because he didn't respond and she apologized for texting so late the next morning. 

Am I being dicked around or is she exploring. She treats me like her significant other when I'm around but I can't help but feel she is sceptical of me for breaking her heart once.
<bot>: I guess my question is why wont she tell me her feelings and why would she treat me like her BF if she is not ready to be in one?
