no, it is not so, because in a second relationship, both men and women are scared and take precautions
Nothing happens if you don't allow it. Surely don't approach it as if you need him more than he does you or show that you are 'out of options'. That can make you vulnerable. Always (at least act like) keep the door open to get out until you are really sure.
If you act and behave as - I've been married once, I've a horrible past, I had no love, I had no reason to stay, I feel inferior, I hate myself at times, I long , crave lust for care, protection, I am unlucky, I am clueless...but I am a nice person..(weeping) but you also have option - I'm confident, beautiful, engaging, smart, world-at-my-feet, sunshine-at-my-door, laughter in my breath, dreams of success and joy in my eyes..er..oh yeh ..I was in a relationship once (smiling).. People always treat you the way you want to be treated...suit yourself! The only time they treat you any different is when you don't tell/show them how you want to be treated..chill..
