I've been with my current boyfriend for 2 years and almost 4 months. The past year has been really difficult for him because his mom left his dad who is very sick and can't take care of himself. He is 23 years old and the only other person living in the house with his dad. Of course this has also taken a toll on our relationship. I do love him, but I feel like I should know deep in me that he is the one for me if he really is, and I don't have that feeling. We've talked about having a future and getting engaged, getting married, having kids, where we eventually want to live. I know I'd be devastated if we broke up, but I feel like I should really know it if he's the one. Another thing on my plate is that a guy who I dated in the past has now started texting me again and all of those feelings have come back to the surface. That relationship never ran its course because he was leaving for a grad program in Oregon at the time and we never got too serious to begin with since we both knew he was leaving. I was shocked that there were even still feelings there after nearly 2 and a half year. I don't want to leave my current boyfriend, but I also don't want to end up with the wrong person. What do you think?
