confused if divorce was the right solution ;o(

Hi,
Im 31 years old, currently living alone and see my kids during weekend only.My story is like this:
I had an arrange marriage which my parents forced me into when I was 17 years old. I got married at the age of 18 years old although I did not love the guy and I did not have any feelings for him.Family pressure was upon me and I was too unmature to reject their decision.I tried to adapt to my husband and his family. Got 2 kids, but things did not change and I felt very incomplete. It was like there was a vacuum in my life.I wanted to divorce but did not have the guts to do it.When one day, some friends encouraged me given I was not happy.I separated and moved to a rented house. I did not have my family to support me so I could not take the kids. They stayed with my ex in-law and ex husband.I was suffocating and could not leave without them. Then I got an opportunity to go abroad which I took thinking this will change my life.I left the kids behind thinking to take them with me as soon as I can.Things did not go as I wished.I stayed with someone with whom i started to love but I could not forget my kids and this created tension in the new relationship.I finally came back to my country after 2 years.My ex husband agreed to come with the kids to stay with me but to stay as the kids parents only under the same roof with no husband wife relationship.I stayed for 1 year and it did not work.Now he left and I'm on my own. Again I have my kids during weekend only.The one I met in the foreign country wants the relationship again. Not sure what to do. Help please.
