My girlfriend did the exact same thing to me and we only were 40min away from each other and spent about 6 months out of the past year apart. For 4 of those months we were in different sides if the world but made it work. She broke up with me about a month ago but I noticed her get distant about a month before we broke up. She told me the exact same thing that she isn’t happy and needs to work on herself and doesn’t feel like she can be the girlfriend that I deserve but she wants to get back together once she figure her shit out. Obviously every situation is different but it sounds like ours are pretty similar and I feel your pain. What has really helped me is reflecting on the relationship and making a commitment to work on myself. Self love is super important. You are 110% deserving and should be the first person in live to receive all rhe love you have. Your capable of being in a loving relationship that involves some commitment you were half of the relationship you loved so much just as much apart of it as he was (and it sounds like you were putting amor more effort in) you are jjst as capable of feeling that love but from within yourself not someone else. For me practicing self love looks like constantly observing my thoughts and trying to question my fears speak to myself internally like I would speak to a significant other and try and be as mindful and present in tbe moment as possible. I also write in a journal every day and what I am thankful for gratitude and looking at the love I already currently have in my life such as friends and family as really helped me. I try and question my thoughts and fears as much as possible asking things such as are these thoughts serving me is this rational or is it jjst invasive and rude and a waste of my energy. You were more then willing to commit and be what he needed you to be but he wasn’t willing to do that for you so really who’s rhe one that lost here? This is just how I’ve been thinking about things and it’s really helped me to move on and get my mind off things by working on the relationship with myself and what I can control rather then witj others and what I can’t. I know it’s beyond fuckint painful but it could also be a chance to find yourself. My bad I know this is a ramble but your situation resonated with me.
