I am a 28 year old Accountant and I have been with my partner for 4 years. I guess you could call him a serial cheater. He is in a job where he's in contact with the general public and is constantly meeting attractive women and he acts on his impulses. He seems unable to consider the consequences of his actions which always come to light one way or another. Three months ago I decided he was never going to change and we split. But rather than that being a final decision we seem to be going around in circles. He keeps texting or ringing and we have met up several times. He wants to try again. I think mainly because he can't stand the idea of me calling it a day. I keep wondering if I've been too hasty. I have had two relationships before, both of them lasting a couple of years and both were ended by the partner. Do you think we could work it out?
If I answer your question 'could you work it out'. I guess the answer is yes it's possible. Is it likely? Well you would both need to do a lot of good communicating and devise a plan for improving the relationship. It seems on the face of it you don't know when or how to say no and stick to it. I know you had a dominant father and that your pattern is to go along with things but this really is a case of 'do what you've always done get what you've always got'. It does feel as if you need to start taking control and taking care of yourself.
You didn't give details of your partners past but he sounds as if he enjoys the thrill of the chase but isn't able to stay attached once he's achieved his goal. In fact it sounds as if he keeps repeating that pattern with you. He chases succeeds and then the relationships ceases to have value and he chases again. This is of course a way of feeling good and validating himself which when you think about it is quite sad.
So what you seem to have is two people who don't feel they have value unless someone is with them and the more unsatisfactory it is the more it reinforces their own low value of themselves. I think the best thing would be for you both to work out singly or together what your individual fears are. It's your choice of course but there would be those who would say don't waste your energy, tell this man no, and start working out what you really want for you.
