I've had it!

My partner has only accompanied me to my first ultrasound. After my 13 week ultrasound I let him know that the 20th week one would be the best and find out the gender. I've been talking about it for months and have been counting down. Now come the day of he claims to be too exhausted. That he did not plan on being that exhausted. I simply said "no one ever plans to be a thug l, but that's life, only thing constant is change". I'm not just upset about him not coming but because he should not have acted interested if he was not attending.
