No you aren't being crazy. if you two live together ( seems a bit soon but ok) for her not having +1 on the invite is weird. Even if she didn't have it on the invite she had plenty of time to tell people she has live in boyfriend and he comes too. I have a bad feeling she wanted to go there alone. In fact she won't be alone as she will be there with him. I am not a jealous person but this will be a deal breaker.
