Need advice.

Shelby • I love my son! 4/22/19 💙👣
I have been with my boyfriend for 5 months now. And, our relationship is wonderful! He treats me so well, as I do him too... I really do love him. I wouldn't trade him for anything. But, today I went on my Facebook page to find out my first love is engaged to be married.. And, I was devistated. It hit me like a semi truck.. I feel like a horrible person because I was upset after finding this out. Like, my thoughts are it shouldnt matter because i have someone awesome.. but it does. And it hurts.. Am I a bad girlfriend? Am I a bad person Becuase of this? Because, boy I sure do feel like it. Help. :/
