DITTO Londres' posts!
I agree that you guys should be trying to find other living arrangements ASAP!
The tattoo issue, I'm sorry, but that's unreasonable of you to expect (or request) he not do tattoos on certain body parts...like Londres said, it comes with the job.
I would recommend working on your self esteem issues hon. Being pregnant isn't an excuse to behave a certain way, nor does it allow you a "get out of jail free" card when it comes to being difficult or unreasonable.
Hang in there, and concentrate on you and the baby....go out and do something instead of sitting in your room....go for a walk, take a crafting class at the local craft store...something to keep YOU busy and distracted, and something that you'll enjoy and give you a sense of accomplishment. Do you work? If not, getting a job is a great idea too!
That will introduce you to a new circle of friends, which is always fun, plus bringing in the extra money would be great. You could sock it away for the baby.
Good luck hon!
To add...........I don't believe pregnancy should be blamed for the actions one chooses to do or for the words one chooses to say.
I am not sure how pregnancy and low self-esteem go hand and hand. Maybe you aren't feeling your best or looking your best because you are pregnant and fear the bf looking at other women? Not sure.
Why can't you two live with your parents or better yet on your own?
Nowadays people get tattoos pretty much where there is skin and if he starts turning down jobs because a client wants a tattoo in spot that his gf doesn't approve of he loses money. I would focus on the fact he is WORKING and this is part of his work. The $$$ he makes benefits you. If he is professional he isn't looking at the situation sexually, but as more $$$.
I work in the medical field and I can't imagine my husband telling me I can't look at or touch any man's body parts. That goes with the territory so to speak.
I am not saying you are wrong or right, but you should try to view the situation from his view more objectively and not so emotionally and subjectively.
