Afraid to be alone

I was wondering if you really love someone do you just trust and believe in what they say and not worry if they are being loyal or not. Just enjoy your moments together and cherish them. So what that they may be cheating. I wonder does it even matter anyway. Every man cheats. So, if you choose to fall in love, or dont chose to and it just happens, you will be cheated on. So, you might as well not even snoop because you know you will find something. But, you want a warning so you will know to prepare and leave and not get too hurt before he leaves you for the one he is cheating with. So, you drive yourself crazy snooping and get hurt for something that you already knew was going to happen. You would be cheated on. You knew this. So, really who is blame for the pain you are feeling now. Just yourself. He only did what all men do. What you already know. So, you dont want to be alone. And your only option is marry someone who will cheat. So, what do you do. You can be alone and be safe from ever getting hurt. OR you can join a relationship that you know is doomed. So you give up your soul, because you are not comfortable being alone and give in to the con man who promises and you believe. A trained belief that you know is a lie. But, you keep pushing those horrible thoughts out of your head. You just want to believe. You pretend everything is ok...but deep inside you are a mess. You are killing yourself because you are afraid to be alone. Its so so sad.
