My girl forgot me

So this may seem a little petty, but me and my girl just had our 2 year anniversary a couple days ago and tonight I'm home alone sick in bed. She was with some girlfriends tonight and told me she'd call me later in the evening. A couple few hours go by and I figure she's hanging with the girls still, so I just send her a text saying to say hi to the girls and to call me when she's all done. She says, "will do love". That was at 10 pm. I know she has to get up for work early, but here I am at 1:30 am like an idiot still waiting. I know she's asleep now, but I'm just wondering how am I supposed to react to this? When she calls me tomorrow, do I just answer and let it go? To be quite honest, I'm feeling kinda forgotten, but I don't wanna seem too... de-masculated... Any words of wisdom?
