Search Results: not ready for serious relationship

So I've been with my boyfriend for over 2 years
He had a bad childhood (his dad was abusive - beating him and his mum) and then he kicked my boyfriend out when he was 18
So ever since he was 18, he has been living by himself.
And he doesn't have much friends either
He's had 2 previous girlfriends but they were never THAT serious (only lasted 6 months max)

I'm his longest relationship

So anyway, lately he has been upset and I asked whats wrong:
HIM - I've been alone for 10 years now, I have a girlfriend which is you, but I still feel alone, I really wish we could live together so I can wake up to someone, can't we just live together?
ME - I mean I need time, I still want to live with my parents and save abit more
HIM - Whats your goals? How long are you planning to stay with your parents?
ME - I don't know..
HIM - I really need a REAL partner, I will become a certified police officer within 2 years, and after that, I know I'll be stable to get married and have kids, would you be ready after 2 years?
ME - I don't know.. I can't really put a timeline, don't pressure me
HIM - Im not pressuring you, Im just telling you how I feel and my future goals, because if you're not ready to fully commit after 2 years from now, then I need to find someone else?
ME - so you want to be with someone else? You're thinking of it?
HIM - No.. Im a patient guy, but I'll be 30 in 2 years time, Im getting old, I want to get married, I want to have a family, that's all Im saying...

I don't really know what to do..
I love him but I feel pressured :\

He always wanted something from me, but never was ready for any serious relationship. I on my side didn't want any fooling around, so it always ended badly and we never had sex.

He always has kept contacting me even when we haven't even seen each other for a year. Now it has been over a year since we met the last time. Then he was trying to convince me he wanted me to move in with him. I didn't believe him and told him to never come back to tell me those lies just to get me in bed. (because he wanted to sleep next to me, I didn't let him)

So months passed and he kept messaging me every now and then. Usually on Snapchat. Then he got a girlfriend and started to send me pictures of her. They were clearly taken in secrecy from her girlfriend, always a little blurry with a weird angle or something in front of the camera. I didn't usually answer him, but I congratulated him on his relationship. He said thanks.

He still keeps messaging me, what should I do? Is he possibly still trying something? I have tried to not answer, still he keeps doing it, so sometimes I answer him nowadays... But it gets confusing sometimes.
