As the title says. We've been together for 4 months and have both expressed how happy we are together and how lucky we feel to have found each other. Things are very easy and relaxed between us and we have great chemistry.
He works a physical job and is exhausted by the end of every day. He moved here from another country which is quite culturally different and he doesn't have many friends here. He also lives in share accommodation the equivalent size of a walk in closet. He's been drinking a lot of his own after work and smoking weed to help him sleep.
The last 1-2 weeks I've noticed his behaviour change quite dramatically and he's basically fallen off the face of the planet. Last time we spoke I felt like I was talking to the depression and it was saying all these things that simply are not true. I actually feel like he is trying to convince himself that our relationship is bad. He's told me a couple of times that he's in bad mental shape and that he's feeling sad, and I have been bending over backwards for him. Now he seems to want to end the relationship because he's unhappy. Last week he was declaring his love for me to my family at the dinner table!
I'm just really confused and I'm so worried about him and I don't know what to do. He doesn't really have much support to fall back on. Any ideas?
