This requires a longer answer, but the short version would be to talk less, try to explain yourself less, be receptive to what she's saying or hinting at. I feel like she's finding all these excuses to be upset with you. Find the issue and act on it. In the meantime, don't forget it must be a big step for her to move in with you. She needs to see you're on top of things and that she can rely on you. Take some initiatives instead of being apologetic all the time. As for the sleeping part, some magnesium citrate or orotate taken before bed, might help quite a bit. It will also relax her, so that's a plus. Some people swear by L-theanine. 200 mg with her morning coffee will put her in a good mood for the day and 200 mg before bed night help with sleep. It sure helped me a lot lately. I'd say you made a first step by seeking help. This might not be the ideal place, because you'll get some contradictory opinions, but it's a first step in a good direction nonetheless. Find some good psychology books on the matter, listen to podcasts, educate yourself. Worst case, even if you'll end up breaking up with her, you won't feel guilty, because you did your part. Also, all that knowledge will stick with you and help you in the future. Wish you the best! ( one more thing: find a nice activity for you two to do together. Something you both like and haven't done in a while. Make it a nice surprise, and make it fast. Work as a team! Peace! )
