Just getting it off my chest

I am 33, my ex is 32. She left me on Fathers Day. We have twins, 10 yrs. old. I am currently going through a cycle of craziness. See, she had a stroke, and decided to leave me for a diff. life. I am a little heartbroken, but then she went ahead and got pregnant, then tells me she's leaving, and moving 8 hours away. She wants the kids 2 months in the summer.

How do I deal with the heartache my kids are about to go through? How do I deal with my responsibilities for the house, the kids, the full time job, etc? I have no room for anything, and I am constantly stressed out. I don't feel like I am making ends meet, things are going boing all around me and now whenever someone makes a suggestion of how I can make their life easier i want to smash them in the face.

I just told my new girlfriend that the reason we don't get much private time is that my kids are 10. She is hoping for more structure. I am hoping for someone to make my world simpler, not more fucking hard. I kept the kids and the house and I don't feel better. I feel abandoned.

I love my kids but can I do this? does anyone have experience going forward in this sort of situation? My ex gets sickly then can't do anything, then she gets well and complains about the kids clothes when I send them over to her apartment. She is a sanctimonious mess to me.

It's simply a roller coaster. I am the dad. I am more stable, healthier, but she makes 10k more a year. Should I be doing this? I don't want my kids lives to change because of her. tldr: fml
