AITA For blocking my best friends significant other after being accused or suspected of getting with her so

My best friend of many years has had history of terrible relationships. And recently she started a relationship with a guy who is absolute sweetheart, i get along with him because he is a genuinely nice person

But recently through a mutual friend of ours i was told that my friend is suspecting me and her bfs relationship

Which got me heartbroken to be honest considering how much i trust her and i was wishing she would trust me.

At first i was mad then i stopped and thought what could i possible done that made her question our relationship

Our mutual friend she told me that i use emojis such as 🥺💕❤️ to him

I do yes but i do that to almost everyone im close with male or female hearts and all

I believe that makes zero sense whatsoever

Then according to our friend she also found it weird how i sent him a photo of me

It wasnt a regular photo i sent

I sent him a photo of me and my newborn niece which i sent that photo to atleast 5 other ppl including a close co worker

She refuses to tlk to me about this on her own so i asked our friend to push her into communicating with me because this is such a wild accusation to me

Until she does i block her boyfriend because i dont need any sort of complications

The only reason i talked to him mainly was because of my best friend i want to keep a good relationship with the person she loves

So am i the asshole? If i did anything wrong or if u wanna ask questions like “did u do that or this” i amwilling to answr and correct my mistakes if i went above the line

Forgot to add i even have a fiance so this complicates the situation too

I informed him of this and he told me that he doesnt see any issues with the emojis or pictures but it could just be his poV

I have been with my fiance for 3 years and my best friend knows that how serious our relationship is too so i feel really down
