How long does it take for you to get over such a long relationship?

Me personally? about a year and that was only a very short relationship, like. 2 months XD. I'm just weird like that

it takes about 2 rebound relationships to get over a long-term relationship

Anyone that has been a "rebound" victim will tell you not to be involved with someone who has just gotten out of a relationship, because you'd be considered as a "rebound" partner. If you do, be cautious! Sometimes, the person may being using you as a rebound to not have to deal with their heartache of the break-up, and they will eventually take out their frustration, sadness, anger, etc. on you. They may be aware or oblivious to what they're doing to you. Maybe it's best to be there for them as a friend for support and allow time for them to heal. If not, you're going to be with someone with "emotional baggage." Time will allow them to re-evaluate their past relationship and hopefully prepare them to be a better partner for the next person they meet. Some people leave a relationship emotionally and mentally healthy and not cynical and jaded. The duration it will take someone to be able to move on after a break-up is dependent on the intensity of the relationship and their desire to let go and move on with their life. Everyone heals differently. His behavior towards you will be a good indication if he has moved on. Your instinct is your best friend. Don't be blind to the signs. Good luck!
