Ok i have a friendship problem?

Maybe you should talk to her in person. Saying it all in a message doesn't completely show her how you feel. Maybe she was too distracted with a new friend and forgot about you. But her reply said sorry, and I'm pretty sure she was sincere. And maybe you can talk to Gabi too. Sit down, buy her a drink and talk about how you miss Emily and that maybe you three should spend time together. And you can politely ask her if you and Emily could have occasional play dates alone. Hope that helped.
