Well said, EskieLover!
Yes, if your gut is telling you this now, it's a big ol' red flag alert!!!
Ending things with this guy now may not be the easiest thing for you...it will hurt a lot, but the pain will be nothing compared to the pain you'll feel if you drag things out. Don't wait for the ***** to hit the fan, do it now, fast and quick, like ripping off a bandaid.
Here's what to expect: the first month or so after ending things you might feel really down, which sucks a whole lot; but after a little while those sad feelings pass, and you'll probably find yourself with this huge feeling of liberation, independence, and freedom...like an "I am woman, hear me roar!" Kinda feeling! Obviously I can't guarantee those results, seeing as I don't know you and don't know all the details of your situation, but that's been my personal experience in a few relationships, and a lot of my friends have experienced the same thing.
You can do it, girl! You can do it!!!!
