"even though I really didn't want to I sent him nude pics of myself"
- No, you did want to.
"I feel I was taken advantage of"
-You're a grown adult, take responsibiity for your own actions. You sent the pics on your terms, not because anyone forced you to.
You two have issues - the trust will probably never be there, what with him sleeping with someone else and you sexting on breaks. I'd suggest you just move on.

If he's made his choice then he's made it. You can only do what you can in apologising and trying to make better decisions- you chose to do what you did and as hard as it can be our actions determine our future. You weren't taken advantage of, as an adult you can decide what you want to do and you could have hung up.
If your partner slept with someone previously and you chose to move passed that, again that was YOUR choice in that situation. You didn't have to, and he doesn't have to forgive you for this either.
I would definitely work on showing him you're trustworthy and worth another shot but be prepared for him not taking the chance
