Without Andre, you'll have to upgrade weapons down paths other than standard that are able to be ascended down with a weapon at +5. For example, Fire and Chaos weapons are still usable. See Category:Dark Souls: Upgrade Paths for a full list of upgrade paths you may be able to take.

For future reference, you can go to Oswald of Carim in order to absolve sin and reset any NPCs who are trying to attack you.
