I would take to heart the advises of female members on this thread river1731, to have a long conversation with your SO, to let her know how you feel, what bothers you and where you think your relationship is headed in general. Assume not a position of an attacker, but a similar position you have taken on this thread, of a concerned partner who feels mistreated in a way and is on a verge of exhausting all avenues.
No need for ultimatums, but the feeling should be, of how long should you be recieving this lack of warmth and intimacy...
Don't cry, don't regret and don't blame
Weak find the whip, willing find freedom
Towards the sun, carry your name
In warm hands you are given
Ask the wind for the way
Uncertainty's gone, your path will unravel
Accept all as it is and do not blame
God or the Devil
