Indie, I don't want to scare you but evaluate Seth well. He may end up breaking your heart too. You need to be strong and rational while going with him. You over-think and that could be your power; power to alert you of coming danger. After each visit, do ask yourself what you liked and what you didn't.
Many a times we keep ignoring things which were constantly hurting us and it is only when all is over that we think of those things. Be alert, be safe.
You are sweet and would definitely get true love in life. And yes, do love yourself and give yourself utmost importance as separated girl advised.
