10 points who ever gives the best advice...?

ok i am with my partner..been together close to 3 yrs.. i have the feeling he is cheating on me .. or just hiding something .. i want to the casino on sunday with my mother he told me i could go.. and i did. he called me a few times telling me he missed me and when i was coming home.. well he was drunk when i got home he never drinks... i thought because of health problems with his grandma he drank to relieve the stress.. so i didnt make a big big deal of it. but today i found out he called someone who number i dont recongize..and spoke over 30mins on the phone this person called him at 11pm while i was away.. he didnt tell me anything about this phone call. he had also talked to this other girl from work and spoke to while i was away.. i think he is hiding something or cheating on me. he got mad cause i confronted him.. but he is at work and couldnt talk about it and i was mad so i hung up on him.. in the past few weeks i know he has called this friend who is a girl from work am i.10 points who ever gives the best advice...?
Just sit him down and talk to him and explain your reasons for these suspicions. Try to keep everything as polite as possible. If he cant sit down and simply talk to you about it then he either isnt worth it or he is cheating so either way he doesnt deserve you. I know you said you have been together for 3 years and its hard to let go but if he doesnt treat you right then let him know and if he doesnt straighten up then break it off for a while till he comes crawling back and give him one chance t redeem himself. If he lives up to them then continue life but if not then just try to move on. Hope this helped and good luck.10 points who ever gives the best advice...?
SET HIM STRAIGHT! u shouldnt xcare if he hurts your feeling tell him how it is tell him what your feeling and why you are. mention the phone calls and girls at work and come up with a solution together.
trust your instincts, I learned that the hard way
