Stress and adding a baby change a marriage.
I'm sorry that you feel this way. Every marriage has its rough spot and this sounds like yours!
Instead of wearing a sexy outfit - try something different - like a nice dinner at home and lots of flirting? I know it helps me when I kiss my husband daily - and I don't mean the peck on the cheek.
How do you keep up your self-confidence when he turns you down? Look in the mirror and say "I've got it going!" Or tell him it's his loss. It may start a fight, yes. But you two need to communicate more...that's what gets a lot of marriages - they forget to communicate - "I've married my soul mate" but that soul mate can't read your mind...for some reason people think that once you get married, everything changes...not much changes if you've been living together before marriage..just the name in some cases...you get into a groove or a rut....communicate...communicate...communicate!!
Thank your husband for his service to our country. As a Navy brat I know that life with a sailor isn't always easy.
I would go out with the girls and have fun too. It's always great to come home after some random guy has just been flirting with you!
