Need advice broken heart

Brittany

There is this guy I been seeing. At first he was really into me. I was weary. Definitely did not want to get my heart broke again. I just got out of a 13 year mental and physical abusive relationship a year and a half ago. Finally healed. This new guy and I agreed we wanted to have a baby together. He already has 4 and I have 3. I love children and children cling to me. He went to Vegas this past week. Instead of asking me to pick him up from the airport he asked my friend. They work together. Yes I trust her if she would have gave him a ride home. Anyway he called and text her while he was there. I messaged him and told him happy birthday. Of course he said thanks back. But that’s the only communication I got out of him. I feel like he has hidden feelings for her and I was just a fill in. What if I am pregnant? I feel as if I should back off even if I am. Am I wrong for feeling that way? My heart is crushed and I saw this coming miles away. 🥺😢😭. Some one give me good advice. Should I keep putting in effort or just move on and move to Florida to get away? I am currently Indiana.
