I have been engaged for 8 years now, like any relationship my fiancé and I have had our ups and downs, this last years was especially difficult.

My fiancé [34 M] was drinking all the time and seemed to have no time for me, when I say it was months in between us having sex I am not lying and on a few occasions when we did he fell asleep during.

At that point my male friend [20] was always there for me he was supportive kind and understating when I was upset with my circumstances, well that is when I started having a big crush on him and found out it was a mutual feeling.

Once I got the courage to bring up how fed up I was with my fiancé that he needed to change or I was done, he has made a 360 turn around , I love him but I think about my friend all the time and I love him too.

I don't want to have to start all over I have worked so hard on this 8 year relationship but now these feelings for someone else are plaguing me and don't know how to deal with them. I feel like a terrible person over all of this.

So what should I do keep trying with the wounded relationship or just up and turn my life upside down for someone new?
