Ok I'm with this great girl who I really love (it's been 1.5 years now) and maybe I am overreacting but i'm not sure:
-I know this guy likes her, and she hangs out with him and his friends on occasion. I have met him, and when I was introduced to one of his friends this weekend, the friend was shocked she had a boyfriend.
-She studied abroad in New Zealand and was miserable. She only made one friend, who was a guy, and she told me he liked her but she would never do anything with him. She came back and on her bday received 22 roses from him. She explained this by saying he likes her but she doesn't lead him on, and he knows she has a boyfriend.
-Today I saw the New Zealand guy had instant messaged her. He said "Hi hon, too bad you're not awake yet." He also called her "sweetie" in the im and signed it "xoxo" with a kiss face. She explains this by saying again that he likes her and talks like that to a lot of girls, but that she can't help it and doesn't do anything in return. She gets very upset everytime I bring up an issue that makes it seems like I don't trust her.
I am trying to have trust here but these signs worry me. Should I be worried? Thanks.
