Is he messing around or is my birth control making me crazy?

Just started taking birth control and I feel a little off balance than normal...

So my boyfriend randomly sends me ;) and I asked him why.

He said he can’t remember but I’m sure there was a reason.

In my mind i imagined him sending

;) to another girl but accidentally sending it to me. I feel like I’m a little crazy to assume this but he’s had a past talking to many different girls and them sending him nudes and what not.

What do you think? Do you think I’m just being emotional or is my gut trying to tell me something?

Thanks ladies
