Can I save my marriage?

[Lll54]

Well I "think" I may have done something good today. So I mentioned that I was going to get the kids their H1N1 vaccinations a week or two ago and that I needed him to help me as we have two young children and I couldn't do it by myself. Today is the clinic and he asked where it is so he could come but I though "no". I don't NEED him to help me. So I arranged for my sister to come help. I told him that and now he hasn't replied to my text about it. I kind of just thought that there are many things in life I may NEED help with but that doesn't mean I need H to help me with them. So I thought today would be a good start to try things on my own. But now he hasn't replied. Is he angry with me? I dunno. Hope I did the right thing.
