should I tell him?

✨Jessica✨ • Bitch I don't like you 😘
Honestly I've been lying to this guy for a long time when we first had sex I told him it was my first time but it wasn't and he thinks he's the only guy I'm having sex with at first it was whatever but I'm starting to feel guilty cause I'm developing feelings for him should I tell him or just leave it another thing we don't use condoms at all but with all the other guys I do
