I think it also comes down the individual person. For me, even when I have a boyfriend, I never let him or let myself change how I act. I still call my Ma and Dad, go out with my siblings, and make time for just me. Yes its harder, but many people let their relationship take over their individual identity. BUT, I do agree that once you have someone, it is harder to let them go. I’ve been going through something for months now where a guy in my life and I are so wrong for each other and it is so hard to let him go. Especially knowing that I’ll have no guy in my life then.
