My boyfriend and cross dressing?

My boyfriend told me that he had been crossdressing and he wasn't sure how it made him feel. Does that mean he doesn't love me anymore? Is he transgender? I told that I loved h and that o accept him no matter what but I'm so scared that this will end our relationship. I care about him so much and just don't know what to do? Should I wait to ask him these questions in person or can I ask them over text?
