Mother's Day ruined...there is a shock!

Well, my husband found a way to ruin mothers day, which really is no surprise! I swear he finds a way to screw up everything. All I wanted this year was a night out to dinner and a 3D/4D ultrasound of the little man that we are expecting in July. I told him this weeks ago and of course he would wait untilTODAY to try and get an appointment. Well, they are booked, and who would expect any different? I know it sounds silly but he works 70 hours a week and I am home with 3 kids all week. I am a full time student and worked my ass off this year to get straight A's. The place is open during the week but my husband works until 8 at night so we would never be able to make it before they close. With the summer coming all of our other weekends are booked for the next few weeks so if I DO go it won't be for weeks. I mean I don't ask for much and the one thing that I want is apparently to complex for him. He his a constant disappointment. I know that I am pregnant and hormonal but this is really what I wanted and it wasn't that hard to set up and I couldn't even count on him for that. All I really wanted was 1 weekend that I could relax, unwind and do something that I really wanted to do but that can't happen to me. I am so upset.
