she never texts when at work ....
She's working.
never replies to my suggestive texts ....
She doesn't like them, but you continue to send them. She NEVER replies yet you continue to do it because you want a certain response. You aren't listening to her by respecting she doesn't want those messages.
never dresses smartly when going out with me but always takes ages to get ready when going out shopping with sisters....
How she dresses is her choice, if you hate it so much then leave.
never wants to try new sexual positions rarely initiates sex but feel she is not emotionally there....
I wouldn't initiate sex with someone who was so focused on me getting 'dolled up' for their approval because I'm an entire person not a blow up doll
gets dolled up for work painted nails glitter on face etc etc
See above.
Almost all your criticisms are about her not dressing / doing make up the way you want her to. The other criticisms are that she isn't sexually adventurous with you and doesn't reply to texts when she is at work, or to suggestive texts she's made it clear she has no interest in.
Do you see the connection between you being fixated on her appearance (which by the way you seem to think is a reflection of you as a person) and her not wanting to be dictated to by you or have sex with you much?
You've every right to prefer a particular look and enjoy certain sexual positions. You have zero right to stay with someone who you resent not adhering to your preferences and expecting them to change who they are rather than leaving them.
