Blindsided.

Hey y'all. just found out tonight that my boyfriend that I've been with for a year apparently has been on tinder for a few weeks and hitting girls up. We were really serious, even looking at rings, so I'm just very blindsided and am wondering who has got good breakup and self care advice for me. I'm just feeling such a wide range of emotions right now, doesn't help that I'm supposed to start my period soon 😑 I dont want to lose my self love or my hope for a good year out of all this so give me all your good ides
