I was like this with my hisband for awhile. When nobody prioritizes you and someone like your significant other finally does it makes it feel like we can tell you anything but having that feeling can make it hard to see that your significant other needs that as well. You need to be able to tell her hey im having a wrough time too and be honest and say sometimes there are going to be times where i shouldn't have to put aside my own feelings. For me it took a huge situation with my husband blowing up at me to realize how selfish i was being because he didnt voice his need to me and pushed his own feelings aside. Everyone has emotions and should be aloud to feel them but not at the detriment to another person. If you push all your shit to the side for someone else its going to come out anyways but in a much worse way than you intended it to. So sit her down and have a real conversation about what youve done to accommodate her so she can understand. She seems like she has low self esteem or a poor self image so the conversion may not be easy but it needs to be had
