i want to share with you another point. my baby brother was also into drugs and alcohol. while he was NOT an abuser and he loved his wife and children dearly - the truth is he loved the drugs and alcohol more.
one night, after doing drugs and alcohol all day he broke into my parents best friends house, while they were home. the couple was elderly and he loved them, they were like grandparents to him. yet, he still made the choice to break in in an attempt to steal gold. the man woke up, and starating chasing my brother thru the house. my brother had a gun - he shot the gun into the floor in an attempt to scare the man, but rather than scare him the bullet ricochet off of the floor and into the man. the man died.
my brother was sentenced to life in prison WITHOUT the possibility of parole. my brother deserves to be where he is.
you are looking at your boyfriend thru rose colored glasses. you can not make him into the man you want him to be. he is what he is, he has shown you who he is yet you because you THINK you love him refuse to believe who he is.
you are young, you are intelligent, you are a loving and caring mother. you have your whole life ahead of you, do not waste one more minute dreaming a dream that can only end up in a nightmare. drugs and alcohol dependecy ruin many many lives - please do not become another statistic.
you need to love yourself enough to take care of yourself. the very fact that you know that doing drugs is wrong is a reflection of the person you are.
sometimes when we think we love someone, we tend to believe that if we only love them a little bit harder, do a little bit more, change about us what they do not like then all will be well and we will live happily ever after - unfortunately that is not true. our loving someone should not be like a sentence for unhappiness. when you love someone they should give as MUCH as they take. i am thinking he is taking all he can - and giving little or nothing in return.
find your strength to build a life for you - it will take some hard work, but if you love yourself enough YOU CAN DO IT. you are fortunate that you have a mom there to help, many young girls have noone.
