Rant about a broken friendship...

This is more of a rant than anything else: I'm not looking for rude comments, please. Even if they are disguised as "just my opinion." My best friend treats me like an idiot and like it's her right to inform me of every possible thing that can go wrong during pregnancy, labour, and post partumm. I've asked her to stop, several times. Her reply is always "if I don't tell you how will you know?" ....I think I'll be ok. Somehow I've made it through 31 years of life without her holding my hand. I also thought about motherhood for years before I decided to give it a go. I'm not a naive little girl who accidentally got pregnant, I'm a grown woman. I have to tell her to stop every time I see her, I actually DON'T want to be around her anymore. Now I understand how friendships end... I really just don't want to see her at all. No one else is any different around me, but she's treating me like a stupid, naive, delicate little flower since I announced my pregnancy at 12 weeks. I'm now 25 and I cannot bear to think of her company for the remaining 15. My biggest regret is making her god mother, I did that at 12 weeks when I announced it to her. ... I want to take it back and have her out of my life. The only thing that has stopped me is that we have been friends for three years and work together. As time has gone on I realize how selfish and self absorbed she is. When her mom died, I naturally offered to help anyway that I can. I took two days off work to support her and drive her every where she needed to go but that wasn't enough. She was mad at me because I didn't want to sleep over. (I'm married, I don't do sleep overs anymore). Anyway, I ended up caving in and sleeping over. I thought we would just hang out and think of the good memories of her and her mom. I didn't realise that she'd invite a fuckboy over and I had to retreat to her kids room all night (kids were with their dad at the time). I could have actually stayed home! She lives in a small apartment, you can hear everything. .. I obviously didn't sleep because I was so uncomfortable so I called in sick for a third day. I went home to sleep, which she was very upset about, because she wanted us to spend all day together. I know she was grieving and everyone is different, but I felt out of place, uncomfortable, and disregarded. ... Another story around the same time: she decided she's a single broke mom, and I'm married with no kids so it was only fair for me to drive across town to her every time we hung out. Again always using the undermining "someday when you have kids you'll understand" excuse. I actually put up with this even though I was unhappy about it because I thought she was still grieving her mom and had all the funeral costs to cover. I didn't realise it would be permanent! It's been over a year and only recently did I confront her that if she wants to see me, she can drive to me for once! and she actually did, but again mentioned that she's single and broke on a one income household and I have a two income household. I told her that she doesn't know my finances, and they are none of her business. If one friend always feels like they are the one putting in all the effort while the other has it easy then something is wrong. It took being pregnant and her never taking my feelings or thoughts into account to realise this is a wasted friendship. I can't keep making excuses for her. She's never been as good a friend to me as I actually made her out to be. I don't understand how I've had her on this pedestal for three YEARS, always compromising for her, and seeing the best in her and now all I see is how utterly selfish she is. I don't know what to do. I think ending the friendship is a bit much and it'll be awkward at work and with all our other friends because we'll keep bumping into each other. I'm done talking and trying not to hurt her feelings. We actually had our first fight the other day because I told her all of this, and she actually apologised. I was relieved, but then a few days later (today) she went on about her horror stories (pooping yourself during birth, vaginal tearing, gouging your eyes out due to ppd, etc. I know it happens, I don't need to hear it). I told her I don't want to hear it, and she again said I need to. I told her I was leaving because this is too much for me and I left. I think I've made it very clear, and she still disregards me. Which is how I got to this rant right now. I just can't do it anymore. I don't want her in my life. I'm done. I don't know what I'm going to do. She's co-planning my baby shower. I just want to cancel everything and focus on my growing family. I'm just so upset right now. She's also a know it all. Telling me what hospital to go to, even though I've said countless times that I love my hospital and medical team and no I'm not switching hospitals just for her! I've never complained about it, why does she fell she has a right to tell me where to go? She

just thinks she knows better because she's had kids and I haven't. What side to lie on, what to eat, what to drink, what to wear. .. I've had it! I need to end this friendship. I was thinking it will be less awkward for work if I do it right before my maternity leave, at the same time I don't want to go through my whole pregnancy listening to her unsolicited advice and it wouldn't be fair to have her be part of the shower then cut her out so I need to do it now.
