My $0.02:
The answer is based on each individual situation, circumstances and history of the couple. I will agree that the MLC portion of problem is definitely on the MLCer and their own issues. However, I do believe there are three basic situations presented on this board:
1) Those that had the "perfect" marriage (i.e. no purposeful neglect, abuse, stonewalling, etc..) and were, for the most part, a good couple.
2) Those that had some marital issues at one point or another, maybe ongoing, that exacerbated the complaints of the MLCer.
3) Those that had major marital issues in conjunction with the MLCer; the marital problems were not only real, they triggered the FOO issues of the MLCer. In this case, I believe you have a combination of a WAS & MLT/C situation.
I personally believe mine falls in between #2 & #3 somewhere! She has major issues of abandonment & "daddy" issues! This was exacerbated by my military career....deployed over half of our marriage; she was forced into "single parent" role while I was off in far away places. I believe the disconnect started a long time ago! She stopped talking about anything, and if I asked what was wrong I got the typical "Nothing" or "I'm fine". Continued lack of communication pushed me away from her to the point where I was neglectful.
Eventually, we were walking parallel paths but we were no longer a "couple". Sure, when we were out with friends, everyone thought we were the model marriage.....facade!
In the end, it's over for us. And that was my call...the LBS made his choice...and it didn't come without self-reflection and fully looking back on the entire marriage, looking for the red flags, looking at my part as well as hers, and the MLC itself! She may be in MLC, and I truly believe she is, but to be honest, we aren't compatible anymore either and I don't think we ever will be! It's sad, and explaining to the kids was the worst part, but D11 seems to be adapting fairly well. No issues at school, no outbursts, none of the typical issues yet that I can see!
That's my particular situation anyway!
