Need your opinion 😔😨😔

My girlfriend is currently 19 weeks pregnant. We have been dating since August '15. We did not planned to have a child this early in the relationship. We live 5 hours away from each other - and mostly visit each other every other weekend. We have had some rough spot in our relationship. She felt I didn't want to be in the relationship - because I said I want to build a strong friendship - but I love her. I felt she wanted to move extremely fast. However, through out the pregnancy she said I have cause her stress and worry - so every week she stop communications with me. This week - it was sparked because she met my family for the first time - and it didn't go as she was expected. They are still getting to know her. I  told her everybody is different - so my family will not react the same as yours. I tried to introduce her to my family prior to this - back in November and December - but she did no want to meet them then. Now she is back saying that I should not be in the child life - and that we should break up. She mention that she can even act like the child is not mine and find some other man. She keep bring up this idea of co-parenting - but I truly don't know what it is. She said it is simple - we decided how much I pay - and when I see out child. I don't think co-parenting is that simple. She will not let me read to baby anymore or touch/rub her belly. I am completely sadden/ heartby this countious uphill battle. All I want to do is love/support her and our little blessing. I want to reach out to see what your opinion were on my situation. Needed to vent.
