im new here and obviously...confused about relationships.
my bf and i have been together for 4 almost strong years, but 6 months ago we only had our first and only "break" that I asked for b/c i thought I was out of love and wanted to see other men. I ended up messing around w/some loser and completely regret it, though I was completely honest w/my bf about it, from the beginning to the end. I think thats what kind of saved it b/c I told him everything. finally after i saw that the grass wasnt greener on the other side, and my bf took me back with open arms, barely any questions. it is now 6 months past, and I thought everything was good (about to celebrate our 4 years) but then he just told me that he wants to go on a break.
He said he wants a break, but not to break up. He said he just wants to focus on trying to forget the past, b/c it always comes back to him. I asked him if we could see other people and he said yes, but I asked him what he would say if asked if he had a gf and he said "i'd probably tell them i was seeing someone else". [note: probably, grrrr] he clearly said he didn't want to stop talking and wants it to do this the "right way", taking a break w/o having anyone on the side, (like seeing someone else).
I completely understand where he's coming from, I know I messed up and never actually took any painstaking crap that I made him go through. He also realizes that alot of my past stems from what he had done also. He knows his mistakes/lies led up to it. The communication is there, it's almost sick to the point where we talk everything out so damn logically.
But now, I don't know what to do. I do feel like a break could be good, but at the same time, all the risks involved is just soooo painstaking. I'm scared I'll lose him to some silly girl or that he'll mess around too. We have always been decently open about talking, but now I'm not sure what to do. He has always been the person that constantly reminds me his love will always be there, but now, that love is open-ended for me.
Should I just stay on the back burner and try not to call him at all and "pretend" to keep myself busy. I know I'm defenitely afraid of being one of those crazy gfs that cries a sob story every night and calling him relentlessly. but i'm weak and sometimes i just cant go a day w/o him

Should I try to make him "almost" jealous or I dont know?! Please help!
