No. Never tell a woman of you were with another one. Always deny, even if there is evidence. If you do get in a relationship and can also start banging the hot one, always hide or archive or delete the convos with her. So even if the cute one looks into your phone, there is no evidence. Also, if you are with the cute one, mute the hot girls messages so you dont get notifications which is a potential risk. Dont share shit that you are in a relationship, because the hot one might not like that, so she shouldnt know about the cute one either. You have to learn to lie too. If the ground start to get hot under your feet, and one of them thinks you cheat, but has no proof, try to avoid answering properly, instead always reply with a question, and try to guilt trip her to feel bad about thinking that you are a cheater. Also, once you start banging the sidefuck, you neednt text her 24/7, so she wont get attached you know, and you can keep your distance, but still not too big of a distance, so whenever you text her you are in town, she still wants to meet. Never invite the hot one to your place, always you go to hers, so the cute girl cant surprise you while you havin fun. Also, you dont have to mention these trips to the cute girl, or anything about that you leave town. If she asks, always have some cover story. And dont make up big stories with lots of details, because that might be strange, and she might realise you lie. If she asks, give enough information that she doesnt ask anymore, but the less she knows, the better.
