I have been in a relationship with my girlfriend for 4 years. Most things about her are great, she is family oriented, she genuinely cares for me, and is exclusive to me. I am currently on break at university and she has been over my house during the winter (I still live with my parents but when I graduate in the spring I plan on moving out). She is usually great to me but whenever she doesn't get much attention due to me working on my business she acts bitter towards me and says that I never care for her etc. This is starting to get very annoying and no matter how many times I call her out on it she always seems to go back to how she was acting in the first place. It has gotten to the point where I wonder about being single and just testing the waters with other women, being she is my first on only girlfriend that I have ever been with I haven't done things with other girls. This is bothering me to the point where I don't feel as though I am working as hard on my business as I could be and if I was single I could use my time much more efficiently. I really care for this girl and share strong feelings for her but I honestly don't know how to handle these feelings. I am seeking advice on this situation that I currently am in. Thanks in advance.
