I too am a WS. Many aspects of your story are the same as mine. I lied multiple times to my BH after he found evidence of my EOA. He really has trouble trusting me now and understandably so. When we lie, we only compound how hard it is going to be to gain trust further on down the road. You said that your girlfriend wanted answers as to why you did what you did, and you didn't have them. I'm in the same boat - it's important to find out the answers though. For her as well as you. Otherwise you are pretty much doomed to repeat all of your behaviors in every subsequent relationship, and you will not only make other partners miserable, but will continue to be miserable yourself. I say this because I see how my behaviors have impacted ALL of my relationships in adulthood & this is my 2nd marriage. I don't want another divorce, but at this point don't know if my BH will stay in the marriage. He is hurt tremendously by what I did, maybe irreparably so.
That's a hard thing to realize you've done, to have so badly damaged someone you claimed to have loved.
So kudos to you for going to IC and trying to get some insight for yourself. I hope your relationship can be repaired, but if not, that you can heal yourself to where you are emotionally mature and healthy. Perhaps even get to a place where you can be in a really good relationship with someone else at some point. I believe most of us WS's are capable of change, even though at times it is overwhelming. However, it is also a matter of willingness as well. Do you want to change yourself? Have you hit absolute rock bottom and are you ready to make some progress forward, knowing even as you take the first step, it's gonna be a painful journey? But so worth it in the end.
BTW - I forgot to make a point earlier in my comment, but I feel it's pretty significant so I'll tack it onto here.
You stated you hadn't met any of your AP's but I assure you that isn't even relevant. I never met the man I corresponded w/ online either but I think that makes no difference, really. Makes no difference in the degree of hurt my BH feels or how very inappropriate it was to go outside my marriage to get my needs met. Whether you do it to get mental, spiritual, emotional, or physical "strokes" from someone else other than the one you're supposed to be committed to is not the issue. The issue is you're asking someone else to fulfill those needs your partner should be fulfilling. I think the fact that the A was online was particularly telling in my case. It wasn't "real" life. It was way easier to hide, way easier to discount, way easier to disconnect from the severity of what I was doing. I'd shut my computer down or turn my phone off and not think about the A or the AP at all. It was very easy for me to compartmentalize it all and put people in boxes and take them out and use them for my own selfish needs whenever I wanted. I didn't even know enough about myself to know that I was weak in certain areas and needed to put boundaries up before I ever even turned my computer on. I met AP through a social media site. I deactivated my account on DDay and haven't been back since. I am surprised at how little I miss it. My BH and I have been spending all that time together that I used to waste online. We've been talking a lot. I'd much rather invest my precious spare time with him than with anyone else.
