I feel as if my girlfriend isn't in love with me anymore.
Our relationship is just starting. It's only been 1 year and a couple days, but we've known each other for 3 years. We are very affectionate with each other and anyone can instantly feel the connection when they are around us. Lately my girlfriend doesn't text me or talk to me on the phone like she normally does. If she's at my house our if I'm at her's, she's normal, however, she hardly acts the same in public. There have been some nights where she would say "I love you too" in an unsure/sad tone after I tell her that I love her. She doesn't like going out much and it's to the point where she has better fun with her friends. I try talking about this with her and all I get as a response is "I love you" or "I promise I'm fine". I try to put the spark back into her but now I don't know what to do anymore. I need help.
