<human>: Can you give me a shortened version of the text?

We broke up 4 months ago cause he said he needed time on his own since we had been together for such a long time. That in addition to him feeling pressure about moving in together (didn't happen). During this time, we became each others best friends and had each other in our long term plans until we broke things off. 

I've tried dating, spending time with friends, working out and working more and its helped until now. 

I just learned through a mutual friend that 2 months ago, he got a girlfriend and they're in love and apparently are planning to settle down together and he even plays dad to her child. From what I've heard, he's also a great BF to her. All the things he's doing for her, I can't help but feel it should've been me. 

That's the part I can't cope with. Any progress I've made just went down the drain. I can't even let go of old photos and he's already erased and replaced me. I guess I knew it was going to happen but not this fast especially knowing he's head over heels in love with her and he's so happy now. I really just need advice to get through this cause I feel like I've been hit by a train. Thanks for reading!
<bot>: ex of 5 years left me 4 months ago to be alone claiming he wasn't ready for commitment but is now committing to someone else. I can't handle it. Advice please.
