1. Start hanging out with your friends and lean on them through the whole "grieving process". PLEASE do not rely on a new man for this process because than you will develop feelings too quickly and things will get ugly. We develop these feelings because he seems so so reliable and he must really care and you can really open up to them about your previous relationship (blah blah blah bullshit bullshit bullshit). He is just trying to get in so do not be so vulnerable when you start looking for a man. If you meet the man of your dreams right after a break up, just tell him you need some time to yourself and if he really cares he'll wait for you (cliche as hell but completely true).
2. Start going out to places you do not normally go so you can get to know a new crowd. There is no point in going to the same bars or house parties that you always go to because than you probably will have a hard time meeting someone new.
3. (MOST IMPORTANT) Do not jump into a new relationship for at least a few months after the break up. That seems like a long time to be single if you were in a long term relationship, but it will really pay off in the end. You need to be completely independent before you start a new relationship. Trust me!!!!
4. When you are finally ready, start a relationship with the guy that always stuck by you and was not just expecting a quick hook up out of you. (sorry for being so graphic but you will meet tons of these asshole while you are "dating")
As I have mentioned before in a previous post, I have made this mistake recently and it really sucks. Because of it I am incredibly bitter and have major trust issues. On the bright side, I hopefully helped someone through my cataclysmic mistakes. Remember, enjoy being single and do not settle for the first guy that you meet. Every guy spits mad game in the beginning, but it does not mean that they will stay that way.
