I need to vent!

So I get my kids from their dads house and they say guess what dad and (his gf) are having a baby. Now some back story their dad and his girlfriend are drunks! So much so that just 2 weeks ago they were both falling down drunk and obviously she was pregnant then because she’s due in August! My ex whom I was with for 10 years! Who said he never wanted anymore kids blah blah now having a baby! I’m hurt angry shocked! Like why the fuck! Me and my husband are healthy! Trying for over 2 years tests and procedures and nothing!!!!!! And here they are pregnant just like that! 💔🙁😡
