<human>: Can you give me a shortened version of the text?

My wife and I have been together since we were 21. Everything (including sex) was great until we got married. Once we did, the sex started going down tremendously. She straight up said "I don't like sex anymore, and I'm not going to do that as much as I used to." She refused to go to a doctor to check hormone levels and refused to go to couples therapy.

Tired of begging my wife for sex, I began sleeping with other women. I probably have had sex with 15 women during our marriage, and messed around with twice that amount.

Now she's pregnant. If I tell her now, I am afraid something could happen during the pregnancy. I don't want her to have a mental breakdown, etc. I know for a fact that at the bare minimum, she will want a divorce. She may even want an abortion.

I'm guessing telling her now is the right thing to do...but is it what I should do?

Thanks in advance.
<bot>: My wife stopped having sex with me regularly during out marriage. I slept with many other women. She's now pregnant. When do I tell her about the infidelity?
