i went through a time with my partner where our sex lives was non existant...but it was on my part! i didn't realize how bad it was or that i was even doing it. i guess after a month and half my partner let me know by asking me whats wrong and how i don't even touch him anymore..i told him that i do i tell him that i say i love yu all the time too. he said no, not anymore (i tend to overuse the word i love you...too many experiences in life where i have lost close friends and never shared my feelings) and it's been ------long . i said he was paranoid nothings wrong with me leave me alone. i went oon like this for half a year when he finally broke down and said i needed to do something, he couldn't take it any longer that was his breaking point i guess....
i found out it was a cross between my medications and mirena that was making me so non participative. and constant pain but i have always had that.

there was a time a little after a year where we questioned our relationship as well, and intimacy was tottaly out of the question, hard to be with someone when you are unsure about them. we have been through a lot together and worked things out, but unfortunatley you need the other person to communicate with you in oreder to do so and the unfortunatley part is thats where relationships dissolve is non communication (easier said than done)
the best approach i personally think when it comes to this subject is to be straightforward...LOok this is what i have been noticing and I need "this" in our relationship I need the connection, I need to feel loved, I don't know whats going on and you won't tell me, so please either talk with me or find someone to talk to. make it all about you how I NEED....just a thought! hopefully i have said something that you can use
