I Am Hurting

I met this guy in kik, he was really persistent to catch my attention, like he would message me everyday and then i found myself responding. We had a great time, i told him that I'm already a mother and he said it's ok. I didn't hide anything to him. Then after a week i told him if we can chat on fb messenger or viber cause someone is harassing me in kik. He told me that he can't give me his messenger because of work etc. So we talk on viber. But my intuition telling me that there is something wrong so i started to ask some random question to get some information so i can find him. His real identity. He was actually responded. I started to search about his job and then there you go, finally saw him. With his real name. So i started to find him on fb, not so hard to find. Then i found out that he is in a relationship. He lied, i confronted him about it. He is sorry and asked for forgiveness, he told me that he was just afraid to lose me that's why he lied about his relationship status. I forgive him, i was already hooked up. We have no label despite of talking every single day. I asked him what i am to him. He said that i am important person to him, and then i became his 2nd party. I am already at his mercy. I find myself waiting for him everyday. I stalked him to found out that he is engaged, the picture of him and his girlfriend makes me decided to leave him for real. He was already happy and i can't bear to see that happiness with his girl. I'm really torn apart. I'm hurting, but i don't want to be a wrecker and not a 2nd choice. I blocked him in any social media that we are connected.I chose to leave today onwards till i forget about him.
