kids ruined your marriage?

I know it sounds AWFUL but I'm pretty sure the kids are putting a strain on our marriage that we just can't come back from. It seems like it's one thing after another and I'm constantly trying to please everyone and it's starting to take a toll on me personally, not just the marriage. I don't know what to do and if I'm being honest, it seems 100% less stressful just splitting up so I can deal with the kids on my own rather than have to deal with my husband too. It's been a long week and I'm really just venting, seriously no need to post rude comments.
