Most Helpful Girl
If I were you, I'd keep my distance. I believe you'll end up hurt if you keep pursuing her. She may have sincere feelings for you but at this moment, it'll be very difficult to distinguish if she truly wants something serious with you or just deeply appreciates your presence while she's going through this difficult process of grieving her marriage. In a way, you are her emotional crutch and that doesn't really place you in a great position when it comes to anything long term. You're filling the void. If you can place your feelings aside and be there for her when necessary, then definitely do. Just don't expect anything in return. At least not for a long time. You shouldn't allow her to pursue things either because in the long run, it's too soon.
I went through the same thing with my previous relationship a few years back and realized that the person I was seeing right after my relationship deteriorated wasn't someone I was in love with and he fell in love with me. I deeply cared for him, built a great bond, appreciated his presence, but overall I didn't allow myself to grieve properly. He was my crutch. I should've given myself some space instead of jumping into a relationship and hurting someone else in the process.
Just let her know you'll be there for her. Be patient. She will insinuate the next step to a relationship when she's ready.
