I agree with Sunny - best to apologise once if you feel you were in the wrong. If you continually apologise and pursue him by text, he withdraws. So, break the pattern. You apologised, and now you can do your own thing while he processes things himself.
It has been on my mind, and I wanted to ask you - I hope you don't mind and feel free not to answer. You said that he has been unfaithful to you a number of times. Have you always been faithful to him, or have you also seen other people whilst the two of you were together?
