I induced a period so my boyfriend would not try to have sex with me?

It's bad to say but we would "get together" after much drink and all I really fancied going back to my boyfr's place was a sleep but he would just suddenly shove his hand down my pants (while i'm fully clothed and not indicating arousal) but this would physically turn me on, as he touched certain parts; so I'd consent to sex even though coerced and after the first few minutes I just wish him to either stop or just get it over with and it all doesn't feel right in the cold light of day.

This would happen for many many many weeks, I rationalised it to myself by having him as my boyfriend; as it somehow makes it right....not sure why.

Some times I knew he wanted sex but got to occasionally induce my period (by taking my pill break earlier but we used condoms) so he'd not touch me and it worked because I would only twice otherwise successfully get him to stop.

Going back to having it easier as him as my boyfriend- this not only allowed me to expect sex every time and to tolerate it; I also conditioned my mind to (eventually!) enjoy him having sex with me and taking control rather than lying and taking it when tipsy!

- Still can anyone put narrative to this weird mess? put labels to this all so I can make sense of it? What could or should I do instead?
