I’m a horrible person !

So I moved in with my boyfriend and his toddler and I feel like... JEALOUS. This is so terrible because I love her, we have had full custody of her all year and I’m the ‘mom’ figure in her life this year. But I just feel like he has to remember to love me lately . Like he’ll wake up and run to see her every morning and he’ll beg me to let her snuggle with us in bed and sleep with us and he always tell her he loves her ,, and NONE of that is bad bc it’s his kid but .. I don’t know I just feel forgotten about! He only kisses me when he’s leaving for work or when we are having adult time , or he’ll only say I love you either over text or in response to me when I say it,

I HONESTLY feel like we have just been together a long time and we r engaged and he just doesn’t feel like he’s gotta put attention / work towards me or this relationship. I’m just jealous of the love she gets,, that sounds terrible but I just am :-(.
