emotional transformation

My relationship of over 3 years recently ended.

It was a mutual decision for this end, but oddly I feel that it was MOST important for my spiritual growth. My ex is not doing well, but I am here for him (just not to the same degree as before). I think this is my time to focus in (soul) and up (higher self). Does anyone have any thoughts about spiritual development and changing relationships? I feel that I outgrew the boundries of our relationship and could no longer fit inside of it.
