I'm writing to ask for advice. I met this guy at work, 5 years ago. I was really into him, at first I didn't know he had a gf, months later I found out. He said he wanted to be friends but he fancied me but couldn't do anything. He would send me very flirty messages, songs, jokes, compliments, pictures from his daily life, apsk for pictures of me - he would show me attention, build it up and then disappear for a week. And then the cycle would continue. He would arrange to meet me then cancel at last minute (I mean 15 mins before). I only saw him a handful of times in person after he left to work in a different branch.
I was infatuated with him even though I knew deep down he was using me to feed his ego. I felt so useless, I kept thinking that if I was better looking, more successful, skinnier he would want to be with me. Whenever I tried to pull away he'd come back texting, sending me songs being all nice, telling me he was thinking of me.
In that time I was seeing other people but nothing serious as I really considered him to be my soul mate and the love of my life and I was hoping he'd break up with his gf, I thought we were perfect together. Nothing ever happened between us physically, although he tried to touch me, stroke my legs but I knew he had a gf and once he got what he wanted he'd just push me to the side. In a way that made it worse.
After 2 yrs of that I got fed up with it and just blocked him, his email, his phone calls, his what's app, his texts. We had no contact with each other for a year and then he phoned me, said he'd like to see me for the good times sake. In that time I met someone who fell head over heels for me, we got engaged and were planning future together. I thought meeting him would provide closure, I thought I was immune to his charms. At first we had a good time, all the good stuff that attracted me to him but without the feelings. We met a couple more times, he was promising he's changed, he was thinking about me and I was his muse. I'd be lying if I said it didn't get to me. Soon my feelings for him starting coming back and that's when I found out I was pregnant with my fiancé. We were very happy and looking forward to our baby but deep down I felt strangely sad like I lost the love of my life and we would never be together again.
Again, I didn't see him for a long time. When I came back to work after a year long maternity leave, we met for a coffee he's told me he broke up with his gf, he cheated on her 3 months after I told him I was pregnant, he blamed me for it (for 'destabilising him' with my pregnancy news), following the break up he started seeing anotherl girl from work 20 years younger (he's 46) than him but they also broke up after few months. He told me he was feeling lonely and regretted that he didn't pursue things with me when he could have had. Obviously it made me think of him but I was focused on my family.
We met up recently in a bigger group of people and my cousin (very attractive and single) joined us. After that night out she told me he was hitting on her whilst sat across the table from me, he was even inviting her over to his. She stood up to him told him she was my cousin and it would be weird (she knew all the history). He didn't take it well and had a go at her. The next day he's asked me for her number to apologise to her.
I gave him a number asking him to apologise but what he didn't know, the number I gave him was a what's app linked to my phone. He started texting 'her', basically saying same stuff he used to say to me. Even sharing songs I shared with him, calling her cute little nicknames he used to call me. I responded as her saying that my loyalty was with my cousin (me) and I would not go out with him. He pursued 'her' every day.
I want to know what you all think I should do, I could just block him or gave a show down or just do nothing. I'm not even angry, I'm so disappointed that he spent years being my friend, flirting with me, pursuing with me, making me doubt my life choices. It meant nothing to him to deceive me so I do not feel bad about deceiving him.
He still texts 'my cousin' every day and invited her for a dinner on Sunday. Am I being unreasonable for wanting to hurt him really bad and carry on with this just the way he did to me?
