Good things: you get someone to spend time with. Frequent sex. Someone to share your world with.b you tell your secrets, you trust them

Bad things: they have their own needs, even when it isn’t convenient for you. You have to accept that you’re a partnership, and their judgement is important. You trust them, whether or not they deserve it. You are open and vulnerable, which means you’re vulnerable. Sex can be mechanical and unfulfilling. Your growth needs to include them

You trade off freedom for companionship basically, but in a good relationship you can still have a good amount of freedom still (you just need to consider the needs of your partner too).

Relationships take effort and compromise; communicating can be hard (but it’s probably the most important thing in a relationship).

Not being in a committed relationship, it’s a lot easier to live without as many obligations.

Also, if you live together you can pool your resources both financially and effort-wise which can help a lot.

Depends on you. Better relationships have better advantages and worse relationships have worse disadvantages. You are the biggest factor across all your relationships.
