I've never been overly insecure like I am now. My husband has never cheated on me either. But I just feel no good. I rarely feel pretty. I always feel like my husband wants someone else (even though he shows no signs) ... I'm just so down on myself right now and need some advice on how to get through it.
Re: self esteem problems. :(
I know there was a period where I felt that I wasn't as attractive to my DH, we sat down and I expressed my feelings. Turns out my DH just didnt want me to be hurt or uncomfortable anymore than I was (due to Sciatica). A solution easily fixed by talking out our concerns and feelings.
Perhaps try talking it out, how else is he going to know what you are feeling like if you don't share it with him.
When it gets bad do something that makes you feel pretty whether it be buying a new dress or doing your hair and make up. Ultimately, if you find this to start creating issues for your marriage or pregnancy talk to your doctor.
Good luck!
