[o0claireo0]

i think ive tipped my girlfriend over the edge looking back now i remember her saying we spend to much time together and stuff nows she says she needs space, shes gone round her mums for a second time now and its killing me ive cryed god knows how many times about it i dont want to lose her its been the best 2 plus years of my life i just dont kno what to do if she wants to be on her own il have to let her but i dont think i really could start dating again i just couldnt replace her and wouldnt want to either...... im scared that i think shes taking the easy way out and wants rid of me but im hoping we can work on it as when she came back the first time time she said she still loved me but didnt kno if she wanted to be with me but she cried and said she still loved me i said i need to know stright and she couldnt make her mind up so went back to her mums why do girls need space surely if you didnt think it would work youd do the right thing and tell them is she feeling hurt herself
