He gave back key and now won't stop calling

[beachgirll2011]

I have been with my b/f 8 months. We are both in our mid 30's neither of us have ever been married. I had a miscarriage in Feb and would like to be in a committed rel so i can try again. In May I told my b/f i wanted to break up b/c he seemed to not want to move forward with the relationship. He constantly used his 8 year old son as the excuse (he said he might go for full custody) plus stuff like his life isn't in order. He wouldn't let me go so we stayed together. At the end of May my lease was up. I talked about moving in and he suggested I look for a place closer to work and him. When he found a place driving to his job one day he suggested I look at it. I luved it but he decided he wasn't ready. I told him I wouldn't move unless it was to move in together. I stayed put. I brought it up again 2 days ago but was more serious. 2 days later he dropped off the key to my place by sending a txt saying he would be at my place in 10 min and if I wasn't there he would leave the key on my kitchen shelf (which he did). I left before he got there and called his bluff and refused to answer his calls/texts which have been at LEAST 5 a day. He was upset I took him off FB and asked if I wanted to end things like this and asked me to call him and stop wasting his time so he can move on. I didn't reply so he wrote he guessed it would be better to talk in person and wanted to meet me during the week. I responded that if he thought our rel was a waste of time he SHOULD move on and that there was no reason to stop by because he made it clear he didn't want to commit when he dropped off the key. I never answered him after that. He texted me that he gave back the key b/c I broke up with him (not true...I asked for him to move forward) and that he hates to let me go without having a conversation with me. He wrote he loves spending time with me. And just keeps texting and texting. I feel like now I don't want him to move in b/c I can't trust him to not walk out which means there is no future for us. I would like him to make a commitment on his own but based on this what advice do you guys have? I really want to move on but if there is a chance he will move forward I would hate to just give up. He has 5 nieces and nephews all under the age of 10 and they have a rel with us now...we have taken them (2 at a time lol) to hershey, the beach, they luv sleeping over my place etc etc. His son just added me as a contact on his IPOD lol His nephew calls me his g/f I have met his parents and stayed overnight at their house. Yet after all this he can't move forward. I don't know how much longer I can wait.
