Sounds like you answered your own question in a way.

Give yourself some time.

Good friendships take time and commitment.

Relax a bit... spend time with your mates and your girl. Let things develope on the friendship side.

Give yourself some time to explore your sexual feelings... without committing to anything there.

Try not to make decisions based on fear.
Be a good friend and you will have good friends.

Blessings bro
