What should i do ? should i still believe in him?

Believe me, I've had my own experiences with long distances relationships and it has always not worked out very well. I was in an on and off relationship with a woman from Florida for 4 years because she made me believe that she had feelings for me and wanted to move up to Michigan where I'm from. i would see her throughout the year and call her all the time but it wasn't serious in the end. Then I realized she had me really as a call when she can up to visit. I felt so used. Just like a summer breeze ping by from one year to the next. So I met a local woman and got married. So as the phrase goes "There always more fish in the sea!"
