I've been single for about 3months since April...?

-Is it alright for me to move on from a 3yr&11mths relationship? .... Or is there like a time line don't tell me whenever I want.... i want to know what is right... I'm over him... since it was a relationship that Towards the end I was only in because he was insane ... And obsessive ... And it grew unhealthy for both of us towards the last year and I broke it off finally in April when I knew it was effect my emotional and mental health ... I grew depressive ... but that's all over I just want to know how long I have to waitThere is no time line for moving on. If you think you are ready, then do it. However, as a personal rule, I will not date someone who hasn't been out of a long term relationship for more than 6 months.
Okay, now you have a better idea of what to look for so start looking. There is no written set of rules or time line or anything. Whatever you are comfortable with and suits you is what you should do.
You won't be over him until you find somebody else, and even then it might take some time.
