Is he coming back

It has been 3 months now, NC for about the last 3 weeks. We were both still in love with each other but he said he needed space as he couldn't commit. We had been together 6 years, living together for a year. I don't know whether the 'next stage' scared him and he suddenly thought about kids etc.....i put no pressure on him. He also went into hospital and was diagnosed with bipolar which he does not accept and does not take medication. I don't think he will come back which is hard when the love is there but sometimes love is not enough. I tried to fight for what we had but he said it's over.
