What do yall think of this?!

so i get a message off snapchat from a girl i like’s boyfriend. the message is sent from her phone. he said something like this “Why do you message Mindy so much”. I sent back “becasue she is my friend” and “Is it bad that i do?” he sent me “You can message other girls”. Heres some background info on this little deal. me and Mindy have a class together, i met her this year for the first time in that class, we became friends we talk in there when we have free time. she says hi to me when she sees me alot. Yes i do like her but since she has a boyfriend i decided to keep my feelings to myself and not tell her even tho i want to be with her very badly. mindy’s boyfriend John is a bit controlling towards her, he does not let her ride in cars with other guys (Me and her and her best friend Jen were going to go to lunch together becasue we got a class that lets us go off campus and stuf like that, he get pissed at her and she tells me we cant ride together. A bit controlling i think.) BAck to the story. i Text Mindy phone knowing that John has it. saying “She is only a friend a aint trying to get between yall.” he then rants on me saying it weird that i text her like everyday and that he has told her to quit sending Me messages or responding back. and that I need to back off from her becasue “she is my girl” later that same night Mindy texts me from her phone saying it is her. she said something along the lines of “hey sorry about john, he took my phone because we were in a fight and had it for a while, he is pissed at me, dont think that me and you arent friends i like you, i am sorry he ranted at you. have a great christmas. (Now days leading up to this she does not reply to anything i have sent her. So tis being the first time i get a message from her in like a few days makes me wonder if she is telling the truth about what she said. i replied to her K,2 u. so what do yall think about this whole deal? sorry for how long this is and for how many words i misspelled and all the gramatical errors, i am still mad about this and am typing fast. Thanks again any advice on what you think is so much appreciated!!!!
