TMI? or Taken Advantage of?

Jenevieve
Okay, so I got on the IUD in September and my boyfriend seems to be taking advantage of it. I have a good stable job, & he has 2. We have 2 children and I don't wanna mess up our jobs or the life we have now. I know that the IUD isn't %100 effective but he doesn't seem to listen to me when I tell him not to cum inside me. He just does it and says sorry. I've talked to him and have gotten mad at him so many times sometimes I don't even wanna have sex because I know he's not gonna listen. Any advice? I seriously am disgusted by the way it runs down my legs after I stand up. He gets mad at me also because I get mad at him...
