Feeling sorry for ex...

Hello! It's a bit long so please be patient with me... Well, I met this guy in 2007 through a common friend and we sort of became friends immediately as we had so much in common.. Before we knew we started liking each other more than just friends and I told him that I love him... And he said he does too.. We started going out... When we decided to take the next step, We decided to tell our parents and get to know our families more... My momdad liked him but his parents, they didn't... Well, the reason they said is, that I'm not well cultured enough for him... I was so offended, hurt... Not for what they said, but this guy, you won't believe what he said! He said his parents are more experienced than he is, so "obviously" they look at other aspects than just looks and smile... Really? I did my bachelors degree in information technology, I have a decent job, a well educated and loving family, but we are middle class, and his family was a bit well off than ours... His mom accused me that I'm a gold digger.. I dunno what they said but he started acting all weird within a couple of months... He used to be all sweet and nice one day, and the next day he was like, this isn't gonna work out, let's not do this... It's like he was sandwiched between his feelings for me, and his parents... I loved him so much that the thought of leaving him was excruciating to me... Still I had faith that he would accept me for what I am just like my family did... This went on and off till 2010.. Finally one day, he met me at my work place and told me that he wants to breakup and that he met this really great girl a few months ago and  his parents like her a lot too... I confronted him.. How can you see another girl while you're still with me? He was like.. I was always on the crossroads about you... I like you but I'm not sure about you anymore... And he said he doesn't see his girlfriend in me anymore... And he just left... He was my first love, and I tried my best to get him back.. He blocked me on Facebook, his email.. So I thought he really does want to end this.. I was a wreck.. No one could console me, nothing I tried made me forget him and move on.. So unable to stay in the same city, I decided to resign to my job and move somewhere faraway and start over... It partially worked.. 5 hard months and I got a really good offer in another state.. I wanted to be away from my parents, my friends everyone so I took the step... My parents weren't happy about it, as I was their only child and I lived just 10 miles away... But still I needed this... I took the job, and I just became a workaholic, working working... I kind of developed an aversion towards guys at one point too... My parents used to visit me but I never went back to my parents house even for Christmas because I thought I might run to him... I didn't wanna make myself a fool.. I still had feelings for him even after 2 years of this breakup.. Then my mom told me that it's time for me to move on and just have faith that the right guy is waiting for me... I didn't have faith anymore.. One more year passed.. And then, I met this guy who newly got recruited in our team... He was from a different country and different culture, tradition too, but still he had this very like able thing about him, that for the first time in ages, I actually started being friendly with a guy... I was skeptical when he asked me out but eventually even I liked him so I said yes. We started going out, and I think that's what brought my happy self back to me again... I was genuinely happy and felt truly "Loved" by someone for the first time in years... I met his parents.. They liked me! And my parents were a bit off as he is from another country & tradition, but they eventually liked him too... He proposed to me in 2014 and I was over the moon! We had an awesome wedding amidst friends and family and I didn't have to look back.. My man was perfect! Then I knew why it never worked with my ex... And wen i realized it, I was truly happy about the breakup! Else I'd never have met my husband! Well everything was going on well when out of the blue, my ex mails me, saying that he is going through real tough time with his family.. seems that he got into a relation with a girl and she kind of used him and lodged a false domestic abuse case on him and he is going through tough circumstances.. He said he needs me for emotional and moral support because I alone know him.. Really? You agree with your parents that I'm not well cultured, and yet you expect me to give you a shoulder to cry on,? After offending me in these many way? I can't help but feel sorry for my ex but... I feel like he needs someone to talk to, and I want to.. But part of me wants him to be away like always... I'm torn... What should I do? Please don't judge me.. That's why I'm writing this anonymously.. Should I be a friend to him again? Or should I be ruthless? Just pretend I never knew him??? I'm torn!!!
