Have I REALLY done the right thing?

My boyfriend of 8 years has just moved out after 3 months. We had a breakup months ago for 2 years but always kept in touch and then realised we did want to be together. Things were great then past couple of weeks I've been a bit down after my cat dying and busy with work so I guess I was a bit of a nag and moody (woman!). He came home after work Friday and just left! He said he felt like he was living in MY domain and that he's sick of bickering about petty things. I knew we weren't really gettin on but I was ready to make it up to him. We spoke yesterday and he told me not to worry and that he just needs to get his head straight. He were supposed to hook up 2nte but he's ignored my calls. I have been calling alot lol but I'm really upset and hurt. I've just joined here and after reading some posts I decided to text sayin that he can get the rest of his stuff, Ilove him and don't want to fall out but I have to move on and all that jazz! Backing off..is this really the right thing?
