I have pretty good instincts. Usually, if there is something nagging in the back of my head, it will turn out to be right.
Let's just take TG, for example. For the past few months, I got the feeling that he was probably seeing someone, but just wasn't saying anything. I know his patterns, so I figured that if it got serious enough, I'd eventually find out. It turns out that I was right, just I never would have guessed what was really going on.
Another time, a close family friend was dating a guy that I just.did.not.like. I mean, I loathed this guy and had absolutely NO reason. To the point that other people thought I was being completely rude and unreasonable. I very rarely cannot stand someone. And, even less am I unable to hide my contempt. About 99% of the time, even if I'm not super fond of a person, I can try to find at least one thing appealing and then tolerate them on that level. But, not this guy. He is one of a handful in my life that I was downright hostile towards. A few months later, we found out that this guy had a HORRIBLE past and was worse than I could have imagined.
This happens a lot, in big or little situations. I will have suspicions or surmise something that I really have no proof about. A lot of times, I won't even say anything to anyone because I fear I'll come off as a crazy person. There are times that I will mention it to a close friend/family, but it's like I will feel the need to list off all these reasons for thinking it..... when, really, it's just my gut.
I don't always end up being right, but I've got a pretty good accuracy rate. I think we all tend to. Our instincts.... our gut feelings.... they are there for a reason. I think God puts it there for a reason.
Trust your instincts and yourself.
