In a relationship and lonely

Hi everyone ,

So I've been with my fiancé for 4 years now and we have a beautiful 1.5 year old daughter together we are trying for number two but are having a few issues.

I don't know if it's being a stay at home mum or just the lack of communication between us but I feel lonely,unloved and unattractive I've spoke to him numerous times about this trying to fix it but I honestly feel like I'm in a relationship with a brick wall does anyone else feel like this with their SO? Most of his time is on his phone or researching things he wants to buy and makes it a little harder to spend time together with his shift work going from days to nights... meanwhile all I want is love and affection I find myself getting excited when someone winks whistle or looks my way purely just to give me a bit of self esteem or attention ! I would never cheat on him or even entertain the thought of it just find myself so deeply deprived of attention that I feel good when I get the slightest bit ..
