k this is stupid i should be smart enough girl to get it but why dont i get it, my boyfriend and i have been dating for 6 years im 23 hes 24 we have a 3 year old son hes awsome. But my boyfriend has issues hes never dealt with plus hes weird he takes methadone nd has been on it fr 3 years hes suposed to stop it but hes weak minded and gives up which is fine addiction isnt an easy thing i get that part. But he treats me very badly hes nice to our son but dosnt take me or wanna do anything not to mention i think hes depressed but i dont kno cause we dont talk as well as ive been sleeping on a couch for 2years and he gets the bed ive been living my life like his i feel like a bad of poop one day he tells me to stay then the next hes telling me he hasnt liked me for a long time now and then tells me to leave then i leve nd come back after an hour then ask him if he really feels this way then he tells me he dosnt kno.....I guess my question really is am i a fool or is this relationship gonna go no where. i feel ive wasted part of my life on him and im still young and why would anyone want to live like this for the rest of my life....im sooooo confused and frustrated plus his parents think its my responsiblity to find my bf a rehab center and im 23 and i dont have an addiction so why do i need to add this extra stuff to my life when i have a son to take care of and im in law school and the last thing i want to do is do what and living my life the way i have been living for the past 6 years. i knew when i met him he was trouble but at the time i was young and nive to believe i could help get on the right path but now we have a kid and im stuck in a hard place hes the "bread earner" in our family he has his own construction company and i do everything for it and i no idea what im doing when i comes to bussiness stuff i study law and would like to persue my dreams but i can't cause i have to manage a bussiness for a lazy guy and do everything and its boring plus i would love to be independent and do my own thing amount to something not being a "mom" to my bf i love himbut its so sad to say more like i care about like hes my son. I want to be with someone who will talk to me and actually have an intelligent conversation with . Am i a ***** and giving up on this guy ?or should i hold out and hope for the best even at risking my own sanity. cause im going nuts on what i want and what he wants cause its hard and im breakingcause its to much for one person to deal with considering the fact that his parents arent there to help him and if i make a wrong desision he could end up doing drugs and not being there as a father for my son and all the hard work counceling and showing him theres life after the darkness of addiction anyways i hope somebody could give me some help or derection in my life that will help me make a hard step in my life or accept that this is as good as its gonna get please give advice feel free to ask questions as well im just like so sick and confused its sad im a good looking girl so ive been told but my bf says if he compliments me then he'll be giving my confidence to meet other guys so hes werid mental games im scared hes gonna break me what do i do?
