I am intern at IT company. and I like someone in my office. he is my senior in my office. We didn't talk in office. because we decided that we are not going to tell anyone about it’s secret. I don't know I like him or not, but I am so desperate for him. I like to see him, talk to him, spend time with him. We met first time last month,we spend some quality time with him. we talked, we kiss each other. after that we were talk on phone calls or what's app in week of 2 to 3 days not very constantly. we talked about relationships we both decided that we are not ready for any kind of commitment or we don't want relationship. we are focusing on career and our priorities in towards to career. and he knew that I am so desperate for him. yesterday we again meet. We did dance, laugh, kiss each other and had sex. but I am thinking I did right thing or not? or he is just using me? I don't want to loose him or his interest in me. Most of the time I texted him.
