He has been your partner for 3 years, and you're about to get married. You're also pregnant

You were about to surprise him at your anniversary, and that’s in 2 days now. You were so excited.

2 days later~

You messaged him and spammed him, but he hasn't replied. However, you remember he said he'd go to the gym.

You went to the gym he said he would go to, but you found him and his ex kissing.
