I met an older women in one of my graduate classes last semester and we hit it off and I began flirting with her right away and ended up asking her out later into the semester which she turned down. She told me that because of a past relationship she has become very cautious and picky about men and doesn't see herself dating anyone. I asked her out again and she did say yes however she got sick that weekend (which I know to be true because she had a doctor’s note and had moved the exam for that week). By this time it was the end of the semester and we had finals and after we finished the last final I asked her out again but this time she politely declined. We talked a few times on the phone after that but then I became busy with some stuff in my life at the time and we lost contact for a month. During the current semester, she and I have another class together. When I saw her from far she walked towards me and we hugged (as we usually do) and kept talking normally it was really good, however from the next time I saw her until now her interactions with me have been all over the place. For example, she’s really kind one second and the next second as cold as ice like I can’t get through her at all. I should also add that she recently she told me she has been stressed out with a lot of stuff which has been going on in her life and she has to take care of many things. I assume this is the reason for the shift in her mood. Now this past week three different guys gave a valentine’s chocolate even though valentine is in week from tomorrow and one of the guys was flirting very heavily with her in front me. I am assuming more will give stuff next week as well. Now before this all began I was planning to send flowers to her work however that is a bit risky because she makes her hours and could cancel at any time if she felt like it so I think the safest thing to do is to send the flower to the class which we are both in so that I can see her reaction too. Now I do care about her a lot but I do not expect to suddenly start dating her after I give her flowers. My main reason is that I want her to know I still care for her and that I am there for her during these rough times and that I can support her. Now here all the questions in my head. First off should I sent flowers to our class even though valentine is 2 days later? Secondly, since she is somewhat of a private person and by giving her the flowers she will be put on the spot, will her mood lighten up regardless? And lastly, after the class I was planning to tell her that I hope her issues which she is dealing with are solved, should I also ask her if she wants to go out on lunch or dinner on Valentine’s Day (I know I said I don't expect to date her but at the same time I want to give it one last shot)?
