I'm so confused😫

I've been with my boyfriend for a little over 3 months but before I got with him I was with this other guy,we broke up 5 months before I got with my current boyfriend but recently I've started having dreams about my ex and I start getting emotional and I honestly don't know what to do I really really like my current boyfriend more then anything but my ex was my first love and lately I can't shake him out of my head😭I don't know whether I still have feelings for him or not but when I'm with my boyfriend I completely forget about my ex but then after he goes I start to think of my ex😭what am I meant to do!?!?
