I think you already know what should be done in your situation…

You say you love your boyfriend, and I believe you. Perhaps the reason you keep cheating on him isn’t a matter of your ability to be faithful or a direct reflection of your relationship with him…

It’s most likely just the fact that you feel that you’ve settled in too early on in your life. You feel like there are so many things that you’ve sacrificed by being in a long term relationship at such a young age; one of those things is, of course, not being able to play the field for a few more years.

There’s nothing wrong with wanting to be single and worrying just about yourself for a while. There is, however, something wrong with wanting to live the single life and being in a relationship. Do this guy of yours a favor, and explain to him that the two of you aren’t on the same page, and that it’s not fair to either of you to continue the relationship if one of you is wanting out.

One more thing… having a great relationship with someone isn’t a feeling… it’s a choice. You’re never going to meet/date a guy who magically makes you know that he’s the one you want to be with for the long haul. Instead, you’ll find a great guy who isn’t always perfect but has the same basic beliefs and goals as you do, and you’ll have to make little choices everyday to help ensure a successful relationship. But it can only be successful if you want/if you’re ready to make it successful. Obviously you’re not ready to commit to this guy for the rest of your days (starting now), so be realistic and end it. Hopefully when you are good and ready, you’ll be able to find a guy who’s as patient with you and who cares for you as deeply as the guy you’re with now does.
