Why capricorn man avoiding me after the beautiful times we shared?

We recently delt with a miscarrage he didnt believe i was pregnant this happen over the weekend i felt pains and i sent him a picture, thing is he never replied back and i ask him if he was with someoen he replies no, but still he doesnt visit me he doesnt pick up my calls, im starting to think soemthing is wrng with me..im going thru enuf, im 21 and he almsot 30 , i cant understand why he doing this to me , not even a simple "leave me alone i cant be with you" can a capricorn man tell em whats really going on..seems like the times we spent together didnt mean anything
