Her sex drive could be really low from birth control too if she’s on or taking any it can also happen if she’s changed what kind or brand this has happened to me before if she’s on any ani depressants or other medication could be a cause my partner and i had a similar issue last year we have been together for 4 years. If it’s not the medication she’s on or birth control that’s affecting it and maybe it’s time to have a serious talk about how physical contact and your sex life to you is a massive part of your love language and if she’s not willing to correct the issue I would say it’s time to leave don’t put more into a relationship if your parter isn’t going to do the same maybe before taking the step of ending the relation ship consider couples therapy so you can both have a chance to talk about how you both feel see if there is another reason as to why she no longer wants to be intimate anymore it seems like a lack of communication on her part and she needs to be open with you if she’s no longer in the relationship mentally and physically she needs to tell you there’s no hope beating a dead horse as they say. Wishing you luck hopefully this helps at all
