Need Advice On Possible Relapse.

Hi everyone, I appreciate any guidance and thank you in advance. So I'm having a very hard time as I'm not sure what to think as I am new to loving an addict. im gonna keep it short for now and get to the point. I've been through 3 relapses with him in the time I've known him. We don't live together or see each other daily but I'm very What I'm not learning to be a co addict and I'm seriously losing it.
So it started about 2 1/2 weeks ago when I noticed he started backing off he had relapsed and just out of treatment and not in any kind of sober living. we talked all the time and he was so sweet then he started blocking my number pushing me away, being very very vulgar and I'll admit I kinda went text stalker as I was just shocked. I do believe on and off that there is another girl but then i don't know. He refuses to give me any explanation. The last time we really spoke where i even caught a glimpse of him was the day after I visited him last weekend so 10 days and he wanted me to come do laundry and couldn't wait for me to see how he rearranged his room. Now I'm crazy ugly he refuses to speak only randomly answers my texts. I know he's around addicts and dealers all day but when he was with me and he was on a binge he went o bed early now he seems to be staying up very late and he just has.no much anger.
Does this sound familiar to anyone as possible relapse signs or am I just over thinking? Do relapse signs make others who're not living with their addict feel like they're being cheated on? Share your stories with me help me understand and how to proceed? Thank you
Get out of the relationship. Its just not worth it. Try alanon meetings because they will help YOU see how easy OUR OWN behavior becomes so irrational.
Kem, have you read the other posts in this forum ?? They are just like yours !!

You have some serious questions about yourself that need to be addressed -
Al-Anon & Nar-Anon could help you get your feet on the ground if you let them.

All the best.
