okay so like my bf cheated on me bc he thought i cheated on him with my ex bc i was talking to my ex (i only dated my ex for like 3 weeks almost 2 years ago) according to my current bf my ex was being too ' touchy' bc he brushed hair out of my face a few times and wiped an eyelash from under my eye off. since this was at a party my bf was a bit drunk. im not sure what i should do...if i should break up with himwhat should i do please explain
