Tristan so far things are going good with you so the only additional advice I will give you is this, now that you've paved the way to a situation where you two are seeing each other again and spending time together, time apart is a good thing. Give her the gift of missing you, you don't have to see each other everyday, it's actually a good thing, time apart does make the heart grow fonder. If you start complaining verbally or more importantly through body language that you want to spend more time together and you don't spend enough time together and you don't like that she spends time at her place when you want her to stay over, it will appear clingy & needy, it will flick switches inside of her that kill attraction between the two of you and that would kill the progress you've made thus far.
Give her the gift of missing you, continue with getting a life and spending time on yourself for yourself, it's healthy, gives you space that you need as you can tell it might feel like you're spending too much time together and your expectations are increasing when this is a time a of no pressure & no expectations.
Start enjoying your life, you deserve it, trust me, give her some space, get a life, spend time on yourself, show her & yourself that you have a life other than trying to fix this marriage, it's attractive to her and it's important for your self-esteem.
