She’s probably not going to tell you if you are a rebound, plus–she might not even know you are until it’s too late and your heart is broken and you’re left sad and confused.
Is she passionate about a personal project but cares little to nothing about telling you about it or involving you at your own free will? Women in relationships with someone they care for, and hope to find a potential future with, will reveal their thoughts and feelings. Is she consistently telling you that you’re perfect, that this is perfect, that everything is great, that you’re going to be together forever and that she wants to meet your parents and pick out baby names?
If your fun times always revolve around the weekends, parties and usually end with her pulling you on top of her and then puking in the toilet with a hangover the next morning, then you may be the rebound.
When you really like someone, you don’t need alcohol to amp up your enthusiasm or dull your senses.
She may not realize it on a conscious level—so be aware and open up the conversation sooner rather than later. And every visit/and or outing involves going home to have a romp? However, there isn’t anything as disappointing as emotionless sex when you’re developing feelings for someone. If there’s limited eye contact, or if the sex is not getting better with a deepening connection each time, then you may be the rebound.
Sex between two people who care about each other becomes better each time, especially in the initial days. Does she not give a shit that you are a devout catholic even though she is an ardent atheist?
