Is the love of my life falling out of love with me?

This May sound weird but I am a bisexual and I've been going with my girlfriend for just over a month it was going great we were great with each other and told each other we loved each other all the time now recently she told me that she sometimes feels she doesn't love me anymore but she said she didn't mean that should I trust her or not? I just can't seem to let go because I'm in love with her

The love of your life isn't going to stop being in love with you. Maybe she's not your true love. You may not even know your true love, and if you do, they may not be in love with you yet. But you don't know who your true love is. But when you KNOW that bf\gf you have is desprate and cares about you more than them, then thats your true love(:
