I am a 28 yrs old guy and I met a girl (26 yrs old) 10 months back through some common friends. She was already in a relationship for last 3 years and had plans of getting married to him. Over the next few weeks we got close to each other and she told me about her bf issues and how it wasn't working out, while she was sorting her issues with him, we ended up having sex one night. Few days later we realised it was wrong and she should either break up with her bf or we should stop our intimacy as we had started to like each other. She broke up with him a week later but wasnt sure if wanted to get into a relationship with me as it was too soon for her to start a new relationship. We kept being intimate for next couple of weeks till she took a month off to travel alone. While on her travels she met some guy for a week and ended up sleeping with him which she told me a week later after she returned. We had a big fight over this but I accepted her back in my life a week later knowing that i really liked her and technically we were not in a relationship when she slept with this random guy (She argued with me over this point) although she did lead me on by calling me every day while she was away but made no promises.
Over the next few months, things got better and we got more and more into each other. We got along really well, and we have never had an argument over anything. There were somedays when she would give me a cold shoulder and tell me it was coz she would be missing her ex bf a lot and wasnt feeling it for me coz she will end up comparing how she felt with him since they were together for 3 years, which i kind of understood. While we were getting serious over the past few months, she started making plans for marriage and convincing me of our future, I had met her family and got along well with everyone and still do. Since i really liked her i convinced myself of thinking long term with her untill a month back she had cold feet again towards me which made me realise its better to put this relationship off than to drag it. She wanted some more time even after 9 months to understand her feelings about us which i wasnt ready to give and i told her we should call it off and not be in touch for a while so that she can think over it and understand if she wanted us together or not, and so we took a break.
Its barely been a month since we broke up/took a break, and i found out through common friends that last week she started to date an old friend of mine who didnt know about our relationship. I dunno what to do and i am so mind fu*&#@ed. I thought i was moving on well without her until now, that she has started dating a friend of mine and was getting cosy with him at a friend’s party. Please somebody advice how to deal with this..? I always had trust issues with her coz of her promiscuous past, and now its turning into a reality.
Should I confront her or let her be? Should i take her off my Facebook and have no contact with her or act all cool and casual and not let her know anything. If i take her off facebook it will show i am weak and insecure, she will be pleased about it, learnt from her last break up with her bf. Or should i just play cool and move on? Pls advice!
