I been a relationship off and on with the same lady for about 4 years...I had intrdused her to a my friend and in about 6s months she kicks me out and goes to him...(yea) and in about 6s months she wants to come back to me.....I take her back she has done this 4 times and she is now with him a gain...I know she will call me.. from one day till the next you never know what she is going to do one day she will tell me how much she loves me..and the next day she will be gone to the other guy. whe I am talking to her she will go clear off the subject. seems like she is either high mood and happy and then in a short time she will be low mood . so I was just wondering if she could have a mild case of bipoler. I love her but can't live this way...she is 55 and I am 65. thank you for any insight to this.
