I met my amazing boyfriend when were 14 and we both went through super toxic relationships and after 13 years of not talking (and some drunk Facebook messaging) We decided to go for a walk at the park to catch up. We have wanted a baby for the last 2 years but decided to stop using birth control last month... So... Holy crap I'm pregnant how do I tell him? Our wedding is next month we figured it would take a little time. I'm freaking out! I have twin boys that are 11 from my previous marrige but I haven't been pregnant in so long. I totally don't know what to do!!! What did you girls do to tell him?
