We have been together for 1 year. My bf (27M) lied about talking to his female friend (27F) to me (23F), and they send each other hearts, kissing emojis, and winks. They have known each other for 5+ years. He claims she's 100% just a friend and there is no other proof he is cheating. They even lightly made vacation plans together for Thanksgiving break and he didn't tell me.
I feel like I cannot trust him after the lying, so in order to make him regain my trust, I need to see he is committed to me.
What should I do?
TL;DR- Bf lied to me about talking to his female friend, now I want him to stop being friends with her.
