Heartbroken - please help :(

This is a long one, il try and keep it brief but im desperate for some help. So I was with my boyfriend for nearly 3 years, in this time we had loads of fun, we took 3 holidays abroad a year, day trips and enjoyed quiet nights in. My issue was living together, after a year and a half I asked him to move in with me and buy a house together he agreed and we started looking, we then had a row over something trivial and he backed out which broke my heart, nevertheless I got on with it and we continued to see each other 4 to 5 times a week and he would stay over. I decided again after another 8 months or so I wanted more, so I asked him again and he agreed, we talked about silly things like pets we would have, 'his garage for his motorbike' etc etc. 4 weeks ago a week after we came back from an amazing holiday to Tenerife he split up with me saying he is not happy he feels he is not himself etc. he cried, I cried he was sick and it was so sad. He left and didn't take his things. He text me a few times and I couldn't resist texting back, we agreed to meet for a meal 2 weeks after the split. after a lovely eve when he dropped me off i apologised for being pushy and maybe grumpy occasionally and he said 'I just can't give you what you want' I left. I didn't text him and a few days later he text and was mad with me for not contacting him, he told also told me that when he left me after the meal he cried all the way home. We agreed to meet again and when I said a week n Tuesday he was mad again and said "'maybe we should just leave it" after telling him he was the one who ended it with me etc he calmed down and we agreed to meet in another 2 weeks. I met him and we went for a drive and ended up playing pool and bowling etc in the arcades. We had great fun and then went for a macdonalds before he drove me home. When we arrived at mine, he said 'do you wanna meet next Saturday' I said 'I need to talk to you first, are we going anywhere as I don't think we can be friends it's just too hard' he got upset and we both ended up in tears, he said he couldn't make me happy and give me what I want, I told him I could wait for a house etc and not pressure him, he said he was no good for me and he knows I want comittment etc deep down. He said I am a lovely person who deserves to be treated like a princess. We held hands and cried for over an hour, I hugged and kissed him goodbye, I told him I could never see him again, the next day (yesterday) I text him and told him I couldn't cut him out my life forever and want to see him, he said if I was sure he would meet me next sat and we would go for lunch and look at cars for me. I want him back more than anything in the world so any advice or insight would be greatly received, sorry for droning on but I figured people need all the info :( by the way I am 27 and he is 25, he is an only child and hate to say this mummy's boy who lives at home, his mum is quite poorly too :( thank you xxx

His problem is that he wants to let go, so you when don't contact him, he gets mad. He needs to stop that craziness. You're doing what you can. It takes two people to make a relationship work. So, ask him what does he really want. Don't let him leave then come back. That's not a good sign.
