Break up

So I decided to break up with my 1st boyfriend. I am 22 years old and I met him when I was 19 and he was 22. I have never been in love, he was my first. But after a year into our relationship I noticed his wandering eyes. this was an issue, if not the only one in our relationship. The 1st time I brought it up with him was about 2 yrs ago. then about 3 or 4 times after that! the last time being a month ago, which ended it for me. I knew this was a deal breaker for me. I am much happier that I don't have to deal with that. he doesn't understand the mental clarity our trial and errors has given me. after forgiving him time and time again. he has proved that his temptations to look are far more important than my insecurities in him. because he has done it over and over. sad things ended like this but am far more happier with myself
