Let's consider some of them:

Pros:

Great trust: When you are in a relationship with someone, you usually share many personal things with your partner. As a result, you become very close, which can lead to great trust and understanding of each other.
Respect: Friendship can be the foundation of a relationship where respect for each other becomes very important. As a result, you will appreciate each other's qualities more and try to make each other happy.
Shared Interests: Partner friends usually find common interests and hobbies that have an edge over regular couples. You can do things you love together and have common goals, which strengthens your bond.
Minuses:

Loss of Friendship: If you end your relationship with your partner friend, you will most likely lose your friendship. It can be very hard and painful if you lose not only your partner, but also your best friend.
Loss of identity: Being in a relationship that is too close can cause you to begin to lose your identity and become too dependent on each other.
Novelty Loss: When you've known someone as a friend for a long time, your relationship can stop being as new and exciting as it started. You may lose interest in each other, which can lead to a breakdown in the relationship.
In general, friendship with a partner has its pros and cons, and everyone must decide what is more important for him - to keep the friendship or take risks and start a romantic relationship. However, if you're both determined to keep your friendship going, then you can enjoy the best of both worlds.
