We Have Finnished.

Can anyone put my mind at rest please. My ex girl friend is 22 weeks pregnant (i am 41 and my ex gf is 27). Iv been with her for just less than a year. but we are not together now. We finnished about 6 weeks ago. She stopped at her mothers house and never been back home. Its really killing me. My heart really is broken. I miss her like crazy. And bump. She says we finnished cos we were arguing and other stuff but to me it was nothing serious. Nothing to break up over. Im allways thinking about her and bump. We went for our 20 week scan the other week we are having a girl We are both really pleased. I miss seeing her being pregnant. Like feeling baby move . When i see her she lets me feel her belly and its great. This is our first baby. But i dont see her much about once a week if that. Im all ways thinking about her. Some people like my family say it could be hormones and she mite come back when baby is born but iv got my doubts. So do any of you girls know if this could be caused by hormones or do you know anyone else this has happened to. Id like to think it is hormones and we will get back together wen baby is born. My head is spinning every day. I think about the. 24/7. She says i can be at the birth and see the baby when she is born. (Due date is sept 23rd). She says baby is stopping at her mothers house . So that means i cant be with my little girl all the time. When baby is born il have to come home without them. And that i cant evan think about. Its guna kill me doing that. She says i cant ring her or text she has to get in touch with me. But im all ways wondering how they both are.

Please help.... Thankyou..
