Every man/woman has the right to be with whomever they choose. No one has the right to let someone fall in love with them under false pretenses and deception. If you’re going to have multiple lovers, it would be wise to let the other ones know. Don’t lie about it-be a man/woman about it. Don’t lead someone into thinking one thing when you have other things going on elsewhere. No one can tell their heart what not to feel. If someone chooses to be the “other” person in your life then let it be their choice. If you take that right from someone with your actions, you are truly a thief.
