Am I a bad friend?

I'm going to try and keep this as short as possible!

I had this friend we grew up together we have always been close she's a few yrs younger then me when she was 18 she had her first baby (id been trying for 2yrs nobody knew) I was happy for her I was always involved in the baby's life even at the birth I was so grateful and happy she's let me share her experience.

A yr later she decided she wanted another baby fast forward I was also at the birth of the 2nd baby too nothing could compare to them experiences it was amazing.

About 6months later my friend and her so broke up she was a great mum until she got involved with this complete waste of space manipulative violent scumbag she ended up falling pregnant very quickly although she struggled with The two she already had. I helped her I was working full time and I dropped everything numerous times to help her when she's been cheated on or beaten up by him I had the kids constantly trying to help her.

A few months later I found out I was pregnant to my shock and delight I couldn't believe it! While pregnant I went to the birth of her 3rd child (as nervous as I was I didn't want to let her down) it was a disaster compared to the first 2 her baby dad had random people turning up he thought the whole thing was was a joke laying all over the bed winding her up giggling, laughing And arguing I couldn't believe what she had put up with from him she changes into a different person someone I no longer wanted to be around.

As harsh as it sounds she went from someone who prioritised her kids to someone who only prioritised him! Shed had a go at me because I didn't answer the phone one time when she had child protection on her case because I was at work because I didn't drop every for her tbh I was getting kinda fed up!

A couple of months along she told me she was pregnant again!! I couldn't believe it she was beyond struggling as it was.

Fast forward my due date was creeping up and I just didn't want her at my birth with all the drama I'd been TTC for yrs and yrs I just wanted to be as relaxed as possible. I had a few twinges one day and she wouldn't stop going on at me telling me what to do and that she knew best I was getting really stressed and snapped at her.

A few days later at 3am I went in to labour I told her i was in labour but she had 3 kids and was pregnant with an unreliable partner I didn't ask her to come to the hospital as she had no one to have the children and thought she might of brung them with her my labour went pretty quick and I gave birth to my beautiful perfect baby!

However my joy was short lived because when my family came to see me the first thing they said was how my friend had been contacting them saying shell never forgive me for not wanting her at my birth she should of been there and that she's missed out she made my life a living hell for the first few months! Telling lies about me making me feel guilty. I'd even invited her to the hospital and to come and see us as soon as she could but it wasn't good enough!

I do feel guilty I did want her there but that was before everything had changed she was a mess and all I'd done is be there for her through everything but I'd had enough of putting myself last i wanted to put me and my baby first and enjoy my time! There were times when she's treated me so badly as a friend I'd never have done that to her I felt as though I was living my life for her and it was wrong she was making bad decisions despite the effect it was having on her children and everyone around her there's so much more to this story but just too much to write down!

I tried to talk to her but there is no talking to this girl the way she was she's just bate your head of the second she heard something she didn't like!

Do you think I was wrong for not having her at my birth? Am I a terrible friend?
