Cheating

Dear Sir, I am a married and divorced woman. In my working place for my fitness often I visit near by fitness studio, there fitness trainer (who is unmarried at that time) has made good friendship with me and he came to know about my divorce, after a good friendship he wanted a relationship with me for life time but I rejected several times because once again I don't want to go through nonsense but continuously he himself pulled me for relationship and pressured me to send my nude pics through whats app. Due to his efforts and my loneliness I believed him and I committed emotionally and physically to him for three months. After three months he got married and settled his own life, so I became silent and side why because I can't make his life he has to live his own life. But he didn't left me as well as he didn't came for me he just keeping me messages and calling me often and video calls only I thought that he is not interested in me and he wanted to hang me just like that. He avoids me by saying that he is so busy, when I stops contact him he suddenly calls or messages me. It hurts me brutally and I am feeling like he is playing with my emotional attachment. I am cursing my self because he himself pulled me into relationship, he himself made me keep and he himself avoiding me I am unable to bare all these things in my life I never expected either economical help (I am scientist with huge salary) or social help I expected his little more companion not complete. He never blackmailed me or abused me. After using me he is skipping from me making me so sad. After getting emotional attachment I am unable to getting out of it. Recently I came to know that he is also chatting, flirting and playing like this with some other women who comes to fitness class. I have all screenshots of his chatting. Is he cheater, If he is what action must be taken upon him under what section he will be punished.
