Tbf I think Charlie’s a dick but he was trying to step up said he would propose to her etc before she got pregnant again and then when he found out she tricked him into having another baby it went south and you could tell he just went off her .. they had many discussions on the show about another baby, he made it clear he didn’t want more and then all of a sudden she’s pregnant
like someone said I think he wanted to have a bit of a life , buy a house etc and probs wanted her to get a job too.. remember when she said she was starting a ‘business’ and he was asking questions and she was shouting ‘WELL I DON’T KNOW CHARLIE’ . All she ever did was shout at everyone
