nope!
no light meets darkness, if she is an unbeliever, if she doesn´t believe in Jesus, her soul is dead, even if she is a nice person, she is unsaved yet, her works can not save her, the only way is Jesus. One reason God didnt want israel men to marry Philistines women, because they didnt belive in God, and even worse, they could provoke israelite men to sin against their God... so if she is not a believer she can make you sin
when a man and a woman marry they become one flesh, so if you marry someone who doesnt belive in Jesus, you will become one flesh with someone who is spiritually dead =/
" For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. " (John 3.16)
