opinions please.

so i’ve been dating my bf for almost a year now. i’m 18. and he is 17. weve been pretty serious and have had no real problems. his ex is crazy and tried to reach out to me multiple times but i ignored it. today i got screenshots from a text now number of another one of his ex’s saying “night babes💗 i love you” but there was no messages from my bf to her. that to me seems more than friends i’m so upset. he’s been so so good to me. opens my door, pays for me, spoils me. my family loves him. i just don’t know what to do. i would never say babe and i love you to a friend. what do i do.
