I'm sure you did what you had to do, and are heading for a better place, if you aren't there already. I just left mine this past week. It was a long time coming, and so far I'm doing really well. I'm sure some days will be better than others, but today was another great day for me.
Who cares what your friends and family think. They weren't in the relationship, so they can't judge what you went through, or what you are going through. No one else can decide how someone else should grieve a loss, so you do whatever feels comfortable for you.
So glad you found us here, you'll find more love and support here than you'll know what to do with! :ghug3
