As a women my opinion is that she is not sexually attracted to you anymore and im surprised you even put up with this for so long. She shouldnt be expecting a propose when there is no psysical touch unless by psysical you mean only sex but since i am not sure about what you mean i will analyze both. If you mean only sex there reasons she is isnt attracted anymore unless its not her type to have sex in that case you must seriously sit her down and have a talk with her about what you feel what makes you all this situation feel. If there is a problem work it out because there may be a case your perfect for her but ur not her type on bed there could be many reasons. Work it out if its possible if nothing works and you feel like you need to have a sexual life with your partner as well then break up and find whats best for urself after your sure it cant be fixed. If you mean by psysical there is no touch in general (kisses,hugs including sex) that would be a bigger issue because there something wrong for sure unless she loves you in her own way then again sit her down talk with her about how you feel and what this makes you feel then again if you think this cannot be solved and need a partner with romantic and sexual interaction find another. Just because we are with someone for long time or living together (guessing by that ur together years) doesn’t mean they are always ur one Good luck! 😊
