I loved my ex. We broke up a while ago and I still have some sort of feeling left for him. I started dating a new guy recently. I like him and he's sweet, but I feel like he's more concerned with partying and hanging out with friends than having a girlfriend. The other day we planned to hang out and when I got to his place, he had friends over and they were getting high. I am against smoking and drinking so I felt disrespected. That's just an example of my current boyfriend's downfall. My ex and I have been talking recently because we can finally be civil and friendly. It just messes with my head because one minute he's flirting and sending me signals, then the next minute he's just acting closed off and uninterested. I don't know what to make of it. It brings up old memories and then I start to feel nostalgic. I like my current boyfriend, but a part of me wonders "what if" with regard to my ex. Can someone give me some clarity/advice?
