Confused

Theresa • Mommy to 3 beautiful baby girls 💕
So my boyfriend has cheated on me a few times and every few months he will go online and make dating account saying he wants hooks up s and stuff like that say he doesnt have a baby(we have a 7month old) and he has girls sending him dirty pictures and videos. I have no clue what to do! I dont want to lose him but at the same time i dont want to be with him
