I would say that you can tell if someone loves you still is by the way they treat you. She could also be destracted with something in her life that she is not talking to you about. I would for your sake and your relationship I would sit down and let her know how you really feel about your relationship.
Well, you have to look for the little signs of love she displays. Does she cook what you like or wear the clothes you prefer? Does she like to sleep close to you or pack your suitcase for a trip? Even little things can help you tell if love is there.
Ignore how often she has sex with you, but look at the other things that she does or does not do for you. Does she pick up the slack willingly if you are too tired or unable to keep an obligation or does she do things for you just because without a reason? If so, then she loves you.
my wife still loves because she is there for me. i work long hours, get up in the middle of the night for calls. its hard for me to be romantic after several domestic assualt calls. i am fussy at times. i think she loves me because she tells me
If your wife still loves you she will show it by her actions. Whether or not she tells you really doesn't matter. . . it's just words. You should be able to tell by the little things that she does or does not do anymore.
Then you'd better get a lot more honest with yourself, and concrete with her, about what it takes for you to overcome your refusal to trust in her love. This is your issue around insecurity, not hers around love..
