So I have a situation that I'm having difficulty navigating, so figured I would post here to get some advice.

For a bit of background about myself, I am a 26M. Have plenty of experiences with dating, including seriously dating as well as doing casual dating, friends with benefits and one night stands (not a simp). At a friend's birthday party, met this really great girl. 28F, had a great conversation with her. She opened up about being separated but not divorced with her ex-husband. They haven't talked for about 3-4 months. Their situation is that they started dating 6 years ago, were long distance for 5 years and got married last year. They are both from the Philippines, and last year she moved to Canada to be with her sister and brother, and the plan was for him to move here too. They messed up their court papers for her sponsoring him to come to Canada, so he was rejected to come to Canada. Then, they tried to do an appeal, and currently waiting on appeal documents (appeal submitted 6 months ago). However, with Covid happening, and her suggesting to see other people and him being hurt over that, they haven't talked for 3-4 months and are sort of separated. I think she still has strong feelings for him, and still wants to end up together with him if possible, but take it both of them don't want to make long distance work anymore. Her mom (who is close to the ex-husband's mom) also said that if they ask for the ring back (ring is expensive) to go ahead and give it back.

Anywho, we hooked up the first night that I met her at the party, and have been casually seeing each other for 3-4 months now. We see each other once a week, and at this point also do a lot of cute dates together (rollercoaster rides, dinners, VR, etc.). When we're out over the past couple of weeks, we've been holding hands. We have some close mutual friends that are aware of our situation and know about it, and she's not the shyest about it. When we first started hooking up, she said that she's not looking for anything serious, and is still getting over her ex. Now I think she's in a spot where she likes me, and cares about me, but at the same time still is in love with her ex-husband and ultimately wants to be together with him if external factors ever sort themselves out. What's curious is even though we've started to PDA more, one mutual friends birthday party, she didn't want us to be a thing, even though ultimately her brother and sister already knew about us.

Over the past couple of weeks, I've realized that I've started to develop feelings for her, and ultimately that I want to properly be with her. At the same time, I think she's not ready for a proper relationship, and is ultimately hedging her bets if Covid resolves itself and visa issues sort themselves out with Phillipines and her ex-husband. My thought is that she's going to ultimately not get over it or decide until all the external things are resolved, she can be with her husband in Canada, and they either agree to be together or realize that now that the external things are resolved, they don't want to be together. My question is this: I want to define the relationship, what I should expect and what I can and cannot do and the reasons behind it moving forward, without putting pressure on her. Or more broadly, does anyone have any advice on navigating this entire situation. I think I can keep my feelings in check and be casual with her, but the lack of clear boundaries and rules is killing me and my overthinking mind.
