So my now ex husband and I got together when DD was around 4 nearly 5, we broke up nearly a year ago after I found out he'd been cheating on me. She's now 14, she still sees him fairly regularly as we have two younger children together, she doesn't see him as much as DS and DD2 do though. She's still quite close to him, sees him as her step dad and he's taken part in raising her. Earlier she asked me why we broke up and I'm really unsure whether to tell her the truth or not. I don't want to hurt her and this of course will and will make her see him differently but it's bothering her not knowing and she's old enough to understand
