My fiancé was calm and easy going when we first started dating. Now out of nowhere and for no reason he will start acting strangely and get mad over nothing and bring up something that we weren t even closely talking about. Then when I ask him why he is getting upset or what is he getting mad about he will say to me that he doesn t know what I m talking about and say that he doesn t know why I always make stuff up in my head. And I will often be going down the hall and pass either the bathroom door or the bedroom or office door and if he s in there with the door closed I will hear him talking to himself. Is there something mentally unstable with him and should I be reconsidering marrying him? Also recently I ve been looking for a job because I ve been out of work for a year now and I m ready to go back to work and he doesn t want me to work and gets upset when I tell him that I applied for a position somewhere. Please shine some light on this subject me. Thanks in advance.
