I make nothing of anything that went on....except maybe staying out all night...that was probably something (bad). So she brought you a cup of wine. So she was nice for 30 minutes. So she texted you her uncle's pic. If she really wants to make a go of this marriage, she'll let you know with more than a glass of wine. How about just being who you are, enjoy what you do have, and not even worry about her for now?
