I once read this on a website and helped me realize that my relationship was going nowhere. Hope it helps to anyone who can relate to it:

A person who doesn’t really love you and doesn’t really want to be with you will constantly leave you questioning everything about the relationship. There will be no certainty, no solid ground. Everything will be fraught with hesitation and doubt and anxiety. He/she will purposely leave you idling in the gray area as long as you are content to stay there so he/she feels safe in the knowledge that he/she always has a “standby” if and when the need arises. You will constantly be walking on quicksand or eggshells. You will constantly struggle to find your footing. He/she will give a little then take away a lot. You will never feel safe in the relationship. The moment you even start to feel safe, he’ll/she'll jerk the rug out from under you just to remind you that he/she, not you, is in control of the relationship. A person who doesn’t love you and doesn’t really want to be with you will drift in and out of your life on his/her own accord and his/her own timetable. He’ll/she'll even leave you feeling as though him/her doing this is a huge favor to you. He/she will subtly let you know that spending time with you is not a privilege but an inconvenience to him/her…so you should savor every precious moment he/she allots to you because you weren’t worthy of it in the first place. (He’ll/she'll do this so subtly, in fact, that it will almost seem charming.) Here’s the thing, though: a person who doesn’t really love you and doesn’t really want to be with you will never, ever REALLY inconvenience himself/herself for you. He/she will never meet you halfway. You will be left to do all the work, all the heavy lifting, all the effort. And you keep doing it because you know if you don’t, you’ll never get to see him/her. A person who doesn’t really love you and doesn’t really want to be with you will never ask you how your day was. Nope…small gestures of thoughtfulness like that aren’t even on his/her radar. The truth is, he/she doesn’t ask you how your day was because he/she doesn’t really care to hear the answer. A person who doesn’t really love you and doesn’t really want to be with you will dodge. He/she will never give a straight answer. He/she will act shady. He/she will disappear for long intervals of time. He’s/She's always “crazy busy.” He/She won’t respond to texts in a timely fashion or at all. His/Her battery constantly “dies” or he/she is perpetually “out of service.” He/she will be largely unavailable to you…always emotionally and often literally. He/She will lie. He/She will cancel plans at the last minute. He/She will leave you waiting for hours. You are more likely hear from him/her at 2:00am than 2:00pm. He/She won’t introduce you to his/her friends. You won’t see any sign of yourself on his/her social media pages. He/She will act single regardless of what his/her Facebook status says. And after a certain amount of time of all of the above and of slowly having your dignity, confidence, and self-esteem chipped away a little at a time…a person who doesn’t really love you and doesn’t really want to be with you will leave you questioning everything about yourself. Why aren’t you enough for him/her? Why are his/her friends more important than you? His/Her work more important than you? Why did you dare speak up and tell him/her that he/she hurt your feelings? That’s probably why you haven’t heard from him/her in weeks. What is he/she doing behind your back? What is he/she doing when he/she vanishes from your life? Why are you not worthy of his/her time, love, and attention? What can you do better, to make him/her love you more? Are you too fat? Too old? Too ugly? Too insecure? Too needy? Too independent? Too MUCH? (The answer to that final question, by the way, is YES. You are too much. Too much woman or man for too little person.) But finally…I should say that all these signs and all this evidence really means nothing, because you answered your question when you asked it. “How do I know if he/she really loves me and really wants to be with me?” You know because you will never have to ask that question of a man/woman who does.

Good luck out there!!
