vent time.. My boyfriend is a senior in high school I'm currently working a full time job and so is he. I've been with this amazing man for 3 and half years. This is our second pregnancy but our first baby. He had mono earlier in the year which had him out of school for a few weeks. He doesn't wanna miss a doctors appointment, having out first baby He doesn't wanna miss a thing. We meet our Doctor for the first time on Monday and I remind his parents so they call the school. Well they "forget" all the time and get him in trouble in school. the schools saying he's missing to much school to graduate. He's talked with the school and they said his parents just need to confirm where you are and your fine. He's talked with his parents and told them he's fine. His teachers actually want him to miss school for baby appointments. I just wish his parents could understand? Am I over reacting, that he's doing fine in school and this is our first baby and he doesn't wanna miss any appointments? His school knows he's having a baby. How do I go about this without stressing myself out?
