How should i feel towards him?

months ago i found out that my husband cheated on me. now he do whatever i told him, he give up his job because he is very near with that girl. he has no work right now and he is taking care of our son. but he doesn't want to talk about the pain i am feeling towards him on what he did to me. i am confused, i don't think he love me that much. i supposed the reason why he still live with me bacause he does't have any choice. his parents house his near with mine, i guess he is just avoiding on what other people will say about us. his relatives thought that he is a very loving and responsible father. i can't help myself not to feel the pain. i can't forget what he did to me. i was in love with him more that the way i love myself before. but now im confused, i want him to feel the heartache that i am feeling. im not sureif he still want me or does he still love that girl. im not sure if he stop communicating with her, or if not, will he still plan to communicate with her again. i need somebody who can rescue me... please help... how should i feel towards him?
