Jealousy

Okay so I’m gonna do a short rant. So I’m dating my best friend of two years (we’ve been dating for two months) and everything is great, I love him so so much and he makes me really happy. BUT the past few weeks I’ve become an extremely jealous person. Like every time another girl touches him or like makes a flirty comment to him I feel like I’m gonna explode. I literally feel like my heart is being torn apart. I’m normally a very calm person and not like this at all so I hate feeling like this. It’s just not me 😞 I don’t know what to do about it and I don’t want him to think of me as obsessive. Any tips on how to deal with this?
