You’re damned if you do damned if you don’t. Or, if you prefer, you’re “stunted” if you stay together and “stunted” if you play the field. The point being both are valuable lessons on the road to maturity. I could tell you to solely trust your gut and stick it through with your bf because you obviously feel that one day in the future you two might walk down the aisle and into the baby nursery together, but I doubt it. Why? Because most young relationships don’t turn out to be the one. This is for various reasons, among them, the need to explore other people and things.
That said, there is much to be learned and gained from committed long-term relationships. Trust, patience, respect and the bonding that can only develop between two people well passed the honeymoon phase are all great things to experience and serve as character builders. So my bottom line here is only you/you two can decide what’s best. Don’t expect it to feel right if you do break up. Don’t expect it to be perfect if you stay together. Relationships such as yours are constantly up for analysis and rechecking – that’s just their nature. So study it! After all you’re in college.
