Low self esteem / confidence

So im 1 year postpartum and well ever since I had my baby my self esteem confidence is very very low, like my belly is all loose skin, i feel fat, i have a double chin, I look at myself and i dont like the person im seeing, i dont like how my clothes fit, i buy nice crop tops then end up changing them to long shirts to hide my belly since it looks like i have 2 . I do plan on getting a tummy tuck but after im done having kids. I have tried working out but then i get soo lazy. Then I found some text messages my husband has been having with his high school “best friend “ she lives in another state and shes married and he told her “you should come back to *names the hometown*” to which she said no because blah blah blah like why would u want her to come back to town? To see her ? I did find another posts on his Facebook from back 2011 and they could “i love you” back at each other so thats why my trust issues w him are low but i love him and I know he loves me but why is he telling another girl to come back to the hometown. I want to feel pretty again because i know im pretty but him not telling me its like dude just calll me beautiful for once 😟😭
